Updates

What changed in sarebamail and in the agent with each version – new features, improvements and fixes.

Version 1.0.0.1563 November 2026

  • Fixed

    Settings menu can be scrolled

    In a short window the lower items of the settings menu were cut off. The menu now scrolls on its own, in the browser and in the desktop app.

Version 1.0.0.1552 November 2026

  • ImprovedWeb interface

    Participants per call by plan

    How many people can join a call or meeting now depends on the plan of whoever starts it – Free and Pro can allow different numbers. Guests via link count too.

Version 1.0.0.1542 November 2026

  • ImprovedAgent

    Two numbers on the icon: green for calls, red for messages

    The agent icon now shows missed calls in a green circle on the left and unread messages in a red one on the right, both with a white number – in the notification area or menu bar, on the Windows taskbar, in the Mac Dock and on the window under Linux.

  • ImprovedAgent

    Paired account in the menu

    Next to “Connected”, the agent menu shows the address it is paired with. That way it is obvious right away when a device is linked to a different account and therefore does not ring for your calls.

Version 1.0.0.1532 November 2026

  • ImprovedAgent

    Choose ringtone in the app window

    “Choose ringtone…” in the menu now opens the call settings in the desktop app window instead of the browser. During a call in the window, or without an embedded web view, it still opens in the browser.

  • Fixed

    Meetings with only guests can start

    A meeting attended only by you and guests via link could not be started. Now it starts quietly with just you when you join, and guests come in once admitted.

Version 1.0.0.1522 November 2026

  • ImprovedAgent

    Missed calls open the app window

    The missed-calls menu item now opens the desktop app window instead of the browser – like clicking the notification. Without an embedded web view it still opens in the browser.

Version 1.0.0.1512 November 2026

  • ImprovedWeb interface

    Privacy policy: locations instead of providers

    Under “Recipients and processors” the privacy policy now names the countries where the servers are located – Austria and Germany – instead of a single provider.

Version 1.0.0.1502 November 2026

  • NewWeb interface

    Report and block in the chat

    Right-click a conversation or use the menu at the top: “Report …” sends a report to the operators, “Block …” means the person no longer finds you in the chat and can no longer write to or call you. The list of blocked people is under Settings → Account – in the mobile app as well.

  • NewWeb interface

    Delete account

    Under Settings → Account you delete your account yourself, and as the owner of a Pro organisation the whole organisation; the Pro admin deletes members under Pro Admin. Final deletion happens after 30 days – until then the account is locked, mail keeps arriving, and after signing in you cancel the deletion with one click.

  • NewWeb interface

    Home page: Made in Europe

    The home page now says where sarebamail is made and runs: developed in Austria, hosted in Austria and Germany, under European data protection law – with an open note on what is touched outside the EU.

Version 1.0.0.1491 November 2026

  • FixedWeb interface

    Stored backups stay readable after stopping

    Anyone who stopped or re-created the automatic backup could no longer open the backups stored until then with the backup password. Now the key of every backup is kept – for the organisation backup as well. Backups whose plan was stopped or re-created before this update cannot be recovered this way.

Version 1.0.0.1471 November 2026

  • Improved

    New icon inside the pages too

    The new sarebamail icon now also appears in the website header, on the sign-in page and on the left of the top bar – in the browser and in the desktop app.

Version 1.0.0.1461 November 2026

  • Improved

    New icon

    sarebamail has a new icon in the style of the sareba programs – on the website, in the desktop app (taskbar, notification area, start menu, Dock) and in the mobile app. At small sizes only an “M” is shown; when the desktop app is disconnected, it shows it in grey.

Version 1.0.0.14531 October 2026

  • NewWeb interface

    Backup: trash and earlier versions

    The backup now also includes the trash of “My files” and the earlier versions of your files. When restoring, what is missing comes back – into the trash with the original deletion time, or under “Versions” of the file. What exists stays unchanged.

Version 1.0.0.14431 October 2026

  • NewWeb interface

    Backup: secure mail attachments

    The backup now also includes attachments of secure mail – encrypted, as they are stored. When restoring, they come back with their message; every attachment is first checked against the message’s signed header.

Version 1.0.0.14331 October 2026

  • NewWeb interface

    Email when there is not enough space for the backup

    If an automatic backup fails because the storage or the “Backup by sareba” package is not sufficient, an email with the numbers is sent – to you, or for the organisation backup to all Pro admins. Once at the first failure, then at most once a week while it persists.

Version 1.0.0.14231 October 2026

  • NewWeb interface

    Backup: mailboxes on the connected mail server

    If your mailbox is on a connected mail server, all folders with all messages plus appointments, contacts, tasks and notes are now included in the backup – also in the automatic and the organisation backup. The backup only reads and changes nothing on the server. Restoring adds: missing items are created, nothing twice, nothing deleted.

Version 1.0.0.14131 October 2026

  • NewWeb interface

    “Backup by sareba” package

    Bookable under Pro Admin → Expand: sareba keeps backups outside your storage in its backup box – they do not count towards “My files”. Members choose “At sareba” for their automatic backup, and the Pro admin can also set up the automatic backup of the whole organisation. Encrypted with your backup key or the organisation’s – sareba cannot open the backups. Restore directly from the list.

Version 1.0.0.14031 October 2026

  • NewWeb interface

    Backup of the whole organisation (Pro Admin)

    Pro Admin → Organisation backup: one file with the state of all members (mail, calendar, contacts, files, chats, secure mail encrypted only, settings) and of shared mailboxes, optionally encrypted with a password. Restoring works one member after another, with the same choice per area as for your own account. Every member sees in their own sign-in log that their account was backed up or restored.

Version 1.0.0.13930 October 2026

  • NewWeb interface

    Automatic backup (Pro)

    Settings → Backup → Automatic backup: daily or weekly at night into the “Backups” folder of “My files”, keeping the last 3 to 30. Encrypted with a key of its own that only your backup password opens. If storage is not sufficient, no backup is created – a clear notice shows how much is missing and leads to expanding it. Stored backups can be restored with one click.

  • FixedWeb interface

    Backup: description and size

    The “Backup” tab shows its description, and “My files” shows the size of your own files instead of the whole organisation.

Version 1.0.0.13830 October 2026

  • NewWeb interface

    Backup of your own account

    Under Settings → Backup you download the full state of your account as a file: emails with folders and rules, calendar, contacts, tasks, notes, your files, chats, secure mail and settings – optionally encrypted with your own password (default). Works on every plan and even with full storage.

  • NewWeb interface

    Restore and chat archive

    A backup can be restored: preview, then per area add, reset to the state of the backup or skip. Before a reset the current state is backed up. Chats go into a separate chat archive to read and search. With full storage you can only read.

Version 1.0.0.13730 October 2026

  • NewWeb interface

    Edit together live

    Text files and documents can now be edited by several people at once in the browser: what someone types appears for everyone else right away, the top shows who is working along, and in documents a named cursor shows where someone is writing. It is saved with “Save” – by anyone, for everyone. Spreadsheets and presentations still ask when saving.

Version 1.0.0.13630 October 2026

  • NewWeb interface

    Edit on the PC and in the browser at the same time

    If a file is saved elsewhere in the meantime (drive on a PC, another window, another person), the editor shows it right away. Text files are merged line by line when saving – including what the PC saves through the drive; only if the same line was changed in both places are both versions marked in the text. For documents, spreadsheets and presentations the editor asks: save anyway, as a copy or reload. Nothing is overwritten – earlier versions stay under “Versions”.

  • FixedWeb interface

    No more empty file after saving on the PC

    When saving through the drive, Windows often creates a file empty first and then writes the content. An empty version appeared in between; the drive now briefly holds back the emptying.

Version 1.0.0.13530 October 2026

  • NewWeb interface

    Edit text files directly

    TXT, Markdown, JSON, log and other text files in “My files” open in the text editor with one click; saving creates a new version and keeps the encoding and line endings. Text files can now also be uploaded through the page.

  • NewWeb interface

    Open with …

    Files that sarebamail does not open by itself now ask on click: text editor, document, spreadsheet, presentation or download. Document, spreadsheet and presentation save a new file next to it; the original stays.

  • ImprovedWeb interface

    “My files” list stays current

    Files added through the drive appear without reloading: when returning to the window and every minute.

Version 1.0.0.13430 October 2026

  • FixedWeb interface

    Renaming and copying on the drive

    Files on the drive (Windows Explorer, Finder) can be renamed, moved and copied again.

Version 1.0.0.13330 October 2026

  • NewWeb interface

    Preparing mailbox moves

    For moving whole domains to the sarebamail mail server, administration now offers a readiness check and an invitation for users who have never signed in. The move itself is still locked.

Version 1.0.0.13230 October 2026

  • FixedWeb interface

    Drive, calendar and contacts in programs

    My files as a drive (Windows Explorer, Finder) and calendar and contacts in programs can be connected again – folder addresses ending in a slash used to be redirected. The Windows instructions are new.

Version 1.0.0.13130 October 2026

  • Fixed

    No update in the middle of a call

    When the server restarted, the desktop app could miss a call and restart for an update. A running call now registers itself again after every restart, and the app waits three more minutes after the call.

Version 1.0.0.13030 October 2026

  • Fixed

    Answering in the desktop app

    When the browser and the desktop app ring at the same time, the app now reliably takes the call: the browser stops ringing right away, and the app no longer reports itself as busy by mistake.

  • ImprovedWeb interface

    Measured reactions in calls

    At most three reactions in five seconds per person, and the sound plays at most every ten seconds.

  • Fixed

    Search at the top within the same area

    A result in the area that is already open (such as an event in the calendar) now opens too.

Version 1.0.0.12930 October 2026

  • New

    The search at the top finds everything

    The search field at the top now searches mail, events, contacts, tasks, notes, files and chats in every area; one click takes you to the result. Ctrl+K jumps into the field.

  • Fixed

    Searching during a call

    The large call window leaves the header free – search and the user menu stay reachable during a call.

Version 1.0.0.12830 October 2026

  • NewWeb interface

    Shared calendars and address books in your calendar program

    Calendars and address books shared with you now also appear in programs such as Thunderbird, Apple Calendar or DAVx⁵ – as a calendar or address book of their own, with the same rights as on the web.

Version 1.0.0.12730 October 2026

  • Improved

    Leaner problem reports

    Reported problems go into the sarebamail team’s ticket system without your address; the log is attached as a file.

Version 1.0.0.12630 October 2026

  • NewWeb interface

    Report a problem with one click

    The small bug icon at the top right opens “Report a problem”. Every report goes straight into the sarebamail team’s internal ticket system – from the browser, the desktop app and the mobile app.

Version 1.0.0.12530 October 2026

  • New

    Call in a separate window

    At the top of the call, “In a separate window” moves the conversation into its own window – the connection stays up, and mail, calendar and search remain usable in the main window. “Back to the main window” or closing that window brings the call back.

  • Fixed

    Keep working during a call

    In the desktop app a video call stayed large over the window after switching to mail, calendar or other areas – the sidebar and search did not respond. It now shrinks to the bottom right.

Version 1.0.0.12430 October 2026

  • NewAgent

    Test ringtone

    In the menu at the agent icon, “Test ringtone” plays the ringtone for a few seconds – to check whether a call can be heard on this device. The log now records when it rang and when the call notification was shown.

Version 1.0.0.12330 October 2026

  • NewWeb interface

    Share calendar and address book

    For mailboxes on the sarebamail mail server: right-click “My calendar” or “My contacts” → “Share …”. With any sarebamail address, as free/busy (busy times only), read, edit or manage; private events stay private. The person receives a short message and sees “Calendar of …” in their list.

Version 1.0.0.12230 October 2026

  • NewWeb interface

    Duplicate, copy and move events

    Right-click an event: “Duplicate”, “Copy to calendar …” and “Move to calendar …”. Title, location, description and time are carried over, without attendees and recurrence; single events can be moved.

  • NewWeb interface

    Schedule a meeting from the calendar

    Right-click a free time slot → “Plan meeting” – the dialog takes over the day and time.

Version 1.0.0.12130 October 2026

  • New

    Report a problem – in the browser, the desktop app and the mobile app

    The user menu has “Report a problem …”: you see the error log exactly as it is sent to us and can describe what happened. In the agent it is “Send problem report…”, in the mobile app More → Report a problem. It is only sent when you click; stored encrypted and deleted after 90 days.

  • NewWeb interface

    Right-click menu everywhere

    Calendar, contacts, files, secure mail and mail security now have a right-click menu like mail. On a calendar: show only this or all calendars, new event in this calendar, Share …

  • NewWeb interface

    Share calendars and address books

    Right-click a calendar or address book → “Share …”: who may see or edit it, right on the folder. For mailboxes on the sarebamail mail server this follows later.

  • Fixed

    Calls on the Mac

    Settings, Help and the other items in the user menu no longer end a running call. The buttons fit into the small call window again.

  • FixedWeb interface

    Images in chat

    An image from the chat opens large in a dark view, without a light bar or border.

  • ImprovedAgent

    Red dot during a call

    The badge on the program icon is red during a call, like the “in a call” status, no longer green.

  • ImprovedWeb interface

    Raising hands in a call

    The raise-hand tone plays at most once every 8 seconds per person – even if someone clicks several times in a row.

Version 1.0.0.12027 October 2026

  • Improved

    Help and texts up to date

    The help describes the device selection for calls and the tip for Bluetooth headphones; minor text corrections.

Version 1.0.0.11927 October 2026

  • New

    Choose microphone, speaker and camera for calls

    Under Settings → Calls and during a call with the gear button – with a test tone and a microphone test. Works in the browser and in the desktop app. Tip for AirPods and other Bluetooth headphones: sound through the headphones, the computer’s microphone for talking – then the sound is no longer choppy. A hint appears in the call.

  • Fixed

    Menus in the small call window

    “React” and “Background” opened behind the floating call window and could not be seen.

Version 1.0.0.11826 October 2026

  • ImprovedWeb interface

    Preparing to move mailboxes

    sarebamail can take over mailboxes from a connected mail server completely – mail with folders, calendar, contacts, tasks, notes, rules and out-of-office. Nothing is moved yet; nothing changes for you until then.

Version 1.0.0.11726 October 2026

  • NewWeb interface

    Prepared for iPhone calls in the background

    An iPhone with the sarebamail app can ring like a phone call even when the app is closed. Apple only receives an empty message without caller or content; the phone fetches the name itself. The app is not in the App Store yet.

Version 1.0.0.11625 October 2026

  • NewWeb interface

    Prepared for calls in the mobile app

    An Android phone with the sarebamail app now counts as reachable: calls ring there even when no browser is open and can be answered in the app – directly from device to device, as in the browser. The app is not in the stores yet.

Version 1.0.0.11525 October 2026

  • NewWeb interface

    Drafts in secure mail

    When writing a secure message there is now “Save as draft”. Drafts appear in the new “Drafts” folder, are encrypted in the browser for your own key and can be opened on each of your devices; they disappear after sending.

  • NewWeb interface

    Always allow or block senders

    In mailsecurity by sareba senders or whole domains can be allowed or blocked permanently – in a list or right on a held message. Blocked ones go to the junk folder, allowed ones are released at once. Release and reject now always sit in a bar above the list, also for several messages at once.

Version 1.0.0.11425 October 2026

  • ImprovedWeb interface

    mailsecurity by sareba on the overview

    Next to “New secure mail” a button of its own leads to mailsecurity by sareba, also in the right-click menu. The “Spam” tile now appears for every account: when not connected, with 0 and a red notice.

Version 1.0.0.11325 October 2026

  • ImprovedWeb interface

    mailsecurity by sareba always complete

    If a mailbox is not yet connected to mailsecurity by sareba, the page still shows its full layout with 0 or “–” and a red notice above it, instead of just a line of text.

  • ImprovedWeb interface

    Consistent wording for connected mail servers

    Help, settings and notices now consistently refer to mailboxes not hosted on the sarebamail mail server as being on a “connected mail server”.

Version 1.0.0.11225 October 2026

  • ImprovedWeb interface

    Tasks like To Do

    Tasks uses the full width: Open, Today, Overdue, Planned, Important and Completed with counts on the left, the list with the quick-add line in the middle, and on wide screens the selected task for editing on the right (otherwise in a window as before). On narrow screens the filters sit as buttons at the top.

  • ImprovedWeb interface

    Wide screens used better

    Settings and administration now sit right next to their menu instead of centred with a wide gap; notes, Pro Admin and mailsecurity by sareba use more width.

Version 1.0.0.11125 October 2026

  • ImprovedWeb interface

    Secure mail uses the full width

    When unlocked, secure mail now shows – like mail – the folders and “New message” on the left, the list in the middle and the open message or the editor on the right. A slim bar at the top holds the status, “Pair a new device”, “Keys, locks and recovery” and “Lock”. On narrow screens list and message appear one after the other.

  • ImprovedWeb interface

    mailsecurity by sareba at the top of the bar

    The mailsecurity by sareba shield now sits right below “Secure mail” with the other areas instead of at the very bottom of the bar.

Version 1.0.0.11025 October 2026

  • NewAgent

    The whole app in the agent window

    The agent's window now shows the same bar as the browser: overview, mail, secure mail, calendar, contacts, tasks, notes, chat, files and mailsecurity by sareba – no longer only chat and calls. In the menu it is called “Open sarebamail…”. Clicking a notification about mail, secure mail or an appointment opens the right place in the window; if a call is running there, the browser opens instead so the call is not interrupted.

  • ImprovedWeb interface

    Secure mail: key stays unlocked

    Once unlocked, the key for secure mail and encrypted chats stays open in this browser – in all tabs and windows and after reloading – until you choose “Lock”, sign out or 12 hours have passed. Until now every new tab and every reload asked again.

  • FixedWeb interface

    Office: “No document given” when creating

    When creating a second new document or spreadsheet, the page occasionally said “No document given”. It now waits briefly until the new document's details are there.

Version 1.0.0.10925 October 2026

  • NewWeb interface

    Overview: “New secure mail”

    Next to “New mail” there is now “New secure mail” (also in the overview's right-click menu). Without a key, the page first guides you through setting one up.

  • ImprovedWeb interface

    The spam filter is now called mailsecurity by sareba

    The tab with the shield in the left bar is called “mailsecurity by sareba” and is visible for all accounts. Its quarantine is currently available for mailboxes on the sarebamail mail server. The home page now shows the features with icons, including secure mail, My files and Office, and mailsecurity by sareba.

Version 1.0.0.10825 October 2026

  • Fixed

    Screen sharing: sharing a second time works again

    If two people shared their screen one after the other or almost at once, sharing no longer worked afterwards. The connection now negotiates changes in order, even when both sides change something at the same time.

  • New

    Call view like Teams, only more flexible

    Everyone in a call may share, several at once. Under “View” you choose Automatic, Gallery, Stage or Arrange freely (drag tiles, make them wider, taller, larger, smaller). Via ⋮ on a tile: show large (pin, several possible), hide (audio keeps playing) or detach into its own window and dock it again. Zoom for shared screens with large buttons. The layout only affects your window.

  • NewAgent

    Agent: count on the app icon, notifications open the agent window

    Missed calls and unread messages now also show on the app icon: on Windows as a badge on the window's taskbar button (green dot during a call), on macOS on the Dock, on Linux on the launcher (e.g. Ubuntu Dock). When a call rings, the button flashes or the Dock bounces. Clicking a chat notification and the “Reply” and “Call back” buttons open the conversation in the agent window instead of the browser. Notifications still only name the sender.

  • NewWeb interface

    End-to-end chats: recovery by the organisation

    If someone replaced their secure mail key, recovery by the organisation's administration now also restores their end-to-end chats – not only secure messages. The member's browser only accepts this if it opens a genuine, signed message of the conversation.

Version 1.0.0.10725 October 2026

  • New

    End-to-end encrypted chat

    When starting a conversation or group you can choose “End-to-end encrypted” if everyone involved has a secure mail key. Only their devices then encrypt and decrypt texts; every message is signed by its sender. Such conversations show a lock; to read and write, you unlock your key right in the chat. Group name, reactions, name and size of announced files, and who writes when are not end-to-end; GIFs and guests are not available there. Existing conversations stay as they are.

  • NewWeb interface

    Arrange your overview freely

    With “Customise” you move widgets by their handle, change width and height at the edge and corner, and hide what you don't need. “Widgets” shows them again or restores the default. Saved for your account, the same on every device; on narrow screens the widgets are stacked.

Version 1.0.0.10624 October 2026

  • ImprovedWeb interface

    My files redesigned

    Side panel with “New”, upload, views and a storage meter (used, quota, free); list with coloured file types, columns and a menu for more actions.

  • NewWeb interface

    Preview for PDF and images, send by email

    Clicking a PDF or image opens a preview. “Send by email” on every file, in the preview and in the editor attaches it to a new email – to recipients inside or outside your organisation.

  • ImprovedWeb interface

    Uploads limited to usable files

    Office files, PDF and images can be uploaded through the page; other files are rejected and named. The drive (WebDAV) and “Save attachment” still accept any file.

  • FixedWeb interface

    Office: page light like paper

    The text and spreadsheet editors now show the page light with dark text in every theme – before, page and background blurred together in the dark theme.

  • NewWeb interface

    Overview: tiles for files and secure mail

    New document, spreadsheet, presentation and upload right from the overview, plus storage and recently modified files. Secure mail shows unread messages and leads straight to writing one.

Version 1.0.0.10524 October 2026

  • Improved

    Security update of all components

    Runtimes, libraries and base images updated to the current stable releases: Go 1.27.3, Node.js 24.22.1 (LTS), Next.js 16.4.3, React 19.3.1, PostgreSQL 16.15. The agent is built with Go 1.27.3.

Version 1.0.0.10423 October 2026

  • New

    Secure mail: unlock a new device with another one

    On a new device choose “Unlock with another device”; it shows a code and a check value. On a device where your key is already unlocked, enter the code under “Pair new device” and compare the check value – then the key arrives encrypted for this new device only. No passphrase or code needed, also in the agent's window.

Version 1.0.0.10323 October 2026

  • NewWeb interface

    Mobile app: notifications without Google services prepared

    The mobile app registers as a device (shown under Settings → Devices, counts towards the device limit). On Android it keeps its own connection to the server and only shows who sent something – without Firebase. The server wakes iPhones via Apple with an empty message only, without sender or content. The app is not in the stores yet.

  • NewWeb interface

    Secure mail: recovery, deputising and log

    If you have lost all locks, set up a new key under “Lost all locks?”; your organisation's administrators recover your earlier messages with their recovery key. If a member allows deputising (can be withdrawn at any time), the administrators can open individual messages of theirs – e.g. during holidays. Everything is recorded in a log with a hash chain, which every member sees for themselves and the administrators see and export in full.

Version 1.0.0.10223 October 2026

  • NewWeb interface

    Secure mail to recipients without sarebamail

    If an address has no key yet, invite it via link when composing: you set a passphrase (a strong one is suggested) and choose how long the link is valid (7, 14 or 30 days). You send the link yourself, e.g. by normal mail, and the passphrase another way. The recipient opens the message in the browser – decryption happens there; after several wrong attempts the link locks itself. Under “Sent” you see whether it was opened.

Version 1.0.0.10123 October 2026

  • NewWeb interface

    Secure mail: attachments

    Files can now be attached to secure messages. They are encrypted in blocks in your browser before they are uploaded; name and type are only in the encrypted text. Recipients download them with one click, the browser checks every block. Your plan's attachment limits apply as for normal mail.

Version 1.0.0.10023 October 2026

  • Fixed

    Status: no longer “away” while you work at the computer

    If the sarebamail agent is running, any mouse or keyboard input on the computer counts for the status – also in other programs, like in Teams. Until now you were away after 5 minutes without input in a sarebamail window, and immediately with only the agent in the background. The agent only reports how many seconds ago the last input was; it is not stored. On Linux for now with GNOME.

Version 1.0.0.9923 October 2026

  • New

    Secure mail: send and receive messages

    The “Secure mail” tab now has Inbox, Sent and “New message”: to sarebamail users with a key – from your own organisation or via the exact address. Subject and text are encrypted in the browser, every message carries the sender's signature and is checked when opened. The agent reports “Secure message from X”, the sidebar shows the number of unread ones. All plans, with a monthly limit; messages do not expire.

Version 1.0.0.9823 October 2026

    Accepting a call from the agent notification with the window open

    If the agent's sarebamail window was already open, “Accept” in the agent's call notification (on the Mac the small window at the top right) could do nothing. Now the open window takes the call directly, without reloading – like its own button. A call already running in the window is not affected.

    Secure mail: organisation recovery key

    Pro admins (for a single account the owner) create a recovery key for the organisation under “Secure mail” – as a whole key or in three parts, of which two are enough, to download or write down. sarebamail stores only the public part with the admin's signature; every member sees the fingerprint and is told about a change. “Check key” shows whether a stored key still matches.

Version 1.0.0.9623 October 2026

  • NewWeb interface

    New “Secure mail” tab: your own key

    Under “Secure mail” you set up a key that is created in your browser and unlocked only there – protected by a passkey (Windows Hello, Touch ID, phone), a passphrase of your own or both, plus a recovery code for emergencies. sarebamail stores only the public part and the locked key. Sending and receiving secure messages follows in the next steps.

  • ImprovedWeb interface

    Mail apps: server ready

    The mail server now accepts connections from mail apps at mail.sarebamail.com – IMAP on port 993, sending on 587 (STARTTLS) and 465. Once the firewall has been opened, the notice under Settings → Apps disappears.

  • NewWeb interface

    Office: ODT, DOC, XLS, ODS, ODP, PPT and PDF too (Pro)

    The pen icon now also opens OpenDocument files (ODT, ODS, ODP), older Office files (DOC, XLS, PPT), RTF and CSV. They are converted for editing and stored in their own format again when you save; the previous version is kept. New: “As PDF” for every document, spreadsheet and presentation.

Version 1.0.0.9423 October 2026

  • NewWeb interface

    Prepared: mail apps via IMAP and SMTP (Pro)

    For mailboxes on the sarebamail mail server, access for Thunderbird, Apple Mail, Outlook and phones is built: incoming via IMAP, sending via SMTP, signed in with address and app password, with the same checks as sending in the browser. Deleted items go to the trash. It can be used once the ports are activated – Settings → Apps shows the status.

  • ImprovedAgent

    Installer for Windows

    The Windows download is now a small installer: it fetches the right version of the agent (x64 or ARM), checks its signature and sets it up. It stays the same file across many versions – so Windows SmartScreen reports “not commonly downloaded” less often. The program itself is still available on the download page.

Version 1.0.0.9323 October 2026

  • NewWeb interface

    Calendar and contacts on your phone and in other apps

    Mailboxes on the sarebamail mail server can now add their calendar (CalDAV) and contacts (CardDAV) to iPhone, iPad, Mac, Android (e.g. with DAVx⁵) or Thunderbird – under Settings → Apps, with one app password per device. Anything an app sends that sarebamail does not show (attendees, photos, birthdays) is kept.

    Pro: extend limits yourself

    Under “Pro Admin → Extend”, Pro admins book add-on packages themselves, such as a larger mailbox, more space in My files or a longer spam quarantine. More applies immediately; less works as long as the organisation does not then use more than allowed.

    Spam filter: no more blocking after one false verdict

    If the spam filter rejects a message, you first only get a notice at the top of the app. Free accounts are paused briefly (outside only) after several rejections and blocked only after many. A message to many recipients counts once; forwarding and mailing lists do not count.

  • NewWeb interface

    Pro: moderation for mailing lists

    Per list: messages from senders who may not post wait for approval instead of being rejected – or every message waits. Pro admins see them in the “Pro Admin” tab under “Mailing lists” (text only), approve or reject them.

  • ImprovedWeb interface

    Mailing lists reach large providers

    If a sender's domain requires DMARC “reject” or “quarantine”, the list sends the message as “Name via List” with the list address as sender; replies still go to the sender. Per list also “always” or “never”.

  • NewAgent

    Unread messages on the agent icon

    Like missed calls, the agent now also shows unread chat messages as a number on its icon and in its menu – even if you were away. A click opens chat and calls (from agent 1.0.0.51).

  • Fixed

    Calls survive a server restart

    When the server restarted (for example during an update), a running call got stuck at “Connection interrupted”. It now reconnects as soon as the server is back. If the other person calls again while the old call hangs, the new call replaces the old one instead of reporting “busy”. During a call the status says “In a call”.

Version 1.0.0.5021 October 2026

    Drag the width of the conversation list and – during a call in the “Chat and calls” app – the width of the chat next to the call with the mouse; it is remembered. The chat no longer slides out of the window.

  • Improved

    Clear message when the server is briefly away

    When the server restarts (for example during an update), the chat no longer shows “Unexpected error”. The bar at the top says the server is not responding and that it keeps retrying; a running call continues directly between the participants.

    Choosing and saving files in the agent window on the Mac

    The background button in a video call led to an error page and ended the call. The menu now opens properly; should something go wrong in the call display after all, the call continues and the display can be rebuilt.

  • New

    Status like in Teams

    Every person now shows a status: available, away (after 5 minutes without input), busy – also automatically in a call and during a meeting in your own calendar –, do not disturb, or offline with “for 2 h”. Choose your own status, a status message and when it is reset via your picture at the top right. With “Do not disturb” nothing rings and the agent does not report messages. “Offline since” can be switched off for others.

Version 1.0.0.4821 October 2026

  • Improved

    Calls in the “Chat and calls” app like in Teams

    In the agent app a call now sits large on the left with the conversation’s chat to its right. The list of conversations steps aside during the call; a button in the header shows it again. In narrow windows the call stays at the top with the chat below.

  • FixedAgent

    “Chat and calls” opens the agent window again on Windows

    On Windows, “Chat and calls…” in the agent opened the browser instead of its own window because Windows rejected the embedded web view. From agent 1.0.0.16 the agent window opens again, at a fitting size on scaled displays.

  • New

    Background in video calls (Pro)

    With the background button in a video call you blur your background slightly or strongly or replace it with an image – built-in or your own. It is computed on your device before the image is sent; your own images stay in your browser. Your choice also applies to the next calls.

  • Improved

    “End-to-end encrypted” in calls

    Next to “Direct connection” or “Via relay” the call now shows “End-to-end encrypted” – as soon as it has been measured for that connection. Only the devices involved encrypt audio and video, also via the relay. Whether nobody sits in between is still shown by the check code.

  • Improved

    Interruptions are shown and bridged

    If the connection to someone drops during a call (network change, dead spot), their image shows “Connection interrupted – reconnecting …” and sarebamail rebuilds it by itself; afterwards “Connection restored” appears briefly. If your own internet connection is missing or the server does not respond, a bar at the top of the app and in the call says so. An interrupted file transfer is fetched again automatically.

  • New

    Files in chat – device to device

    Use the paper clip in the chat (also in the chat during a call) to send files. They go directly from device to device and are not stored on the server; afterwards every recipient has them locally and can open or save them. If a recipient is not online, their device fetches the file as soon as a device with the file is reachable. How large a file may be depends on your plan.

  • New

    Chat during calls

    A button in the call opens the conversation's chat next to it: write messages to everyone in the call without leaving the call window. What you send there stays in the chat afterwards.

  • Improved

    Screen sharing with camera images

    Whoever shares their screen stays visible with their camera. For the others the screen appears large and all participants' camera images in a strip next to it. Whoever joins later sees the shared screen right away.

  • NewWeb interface

    Rules by right-click

    Right-click a message and choose “Create rule…” to set up a filter rule, prefilled with sender and subject – for example “move to folder” or “mark as read”. Filter rules are now also available for mailboxes on the sarebamail mail server (Settings → Filter rules); they apply to newly arriving messages. Forwarding to outside addresses follows with Pro.

  • NewWeb interface

    Pro Admin

    With Pro you get the “Pro Admin” area for your organisation: change the name, see Pro seats and add more at any time yourself, appoint further Pro admins. Every user who can sign in takes one Pro seat; every change is recorded for billing. Own domains and new users follow in the next steps.

  • NewWeb interface

    Aliases for sarebamail mailboxes (Pro)

    Under Settings → Aliases you create additional addresses for your mailbox. Messages to an alias arrive in your inbox, and when composing you choose it as sender; when you reply to a message sent to the alias, it is preselected. Aliases are part of the Pro plan (up to ten); the Free plan does not include them.

  • NewWeb interface

    Create an account yourself

    Once registration is open, you can create a free sarebamail mailbox under “Create account” – with an existing email address as contact or via “I don't have an email address yet”. Without a contact address stricter rules apply, such as a trial period with limits for outgoing messages; which ones is shown on the page before you submit. To protect against automatically created accounts, the browser briefly solves a task when you submit, without picture puzzles and without third parties.

  • NewWeb interface

    Forgot password

    For mailboxes on the sarebamail mail server with a confirmed contact address, the sign-in page now offers “Forgot password?”. The link goes to the contact address and is valid for 30 minutes; afterwards all sessions and paired devices are signed out.

  • NewWeb interface

    sarebamail mailboxes can send

    Mailboxes on sarebamail’s own mail server now send by themselves – with DKIM signature. Recipients on sarebamail get the message immediately; to other servers the mail server delivers with verified encryption where the recipient offers it, retrying for up to 5 days. If that fails, a non-delivery report arrives in your inbox.

Version 1.0.0.4720 October 2026

  • New

    Suppress background noise

    During calls sarebamail now suppresses background noise – where browser and system support it, with voice isolation that clearly separates the voice from the background. A button in the call turns it off and on again without interrupting the conversation; the browser remembers the choice.

  • Improved

    Full screen in calls

    A dedicated button in the call switches the whole call to full screen. In the agent app a video call gets the full height right away; the button next to it brings the chat back below. On the Mac full screen now also works in the agent window, plus the window’s green full-screen button (from agent 1.0.0.15).

  • FixedAgent

    Camera and microphone in the agent window on the Mac

    macOS now asks for camera and microphone when you call in the agent window. Until now the agent’s signature lacked the required rights and macOS blocked without asking (from agent 1.0.0.14).

  • FixedAgent

    Agent no longer quits when answering

    On Windows the agent could quit silently when answering a call if the app window could not be opened. It now opens the browser instead (from agent 1.0.0.14).

  • NewAgent

    Agent in the Start menu

    On Windows “sarebamail Agent” now appears in the Start menu and in search – to start it again after quitting. Please delete older downloaded copies (for example in the Downloads folder) (from agent 1.0.0.14).

Version 1.0.0.4620 October 2026

  • ImprovedAgent

    Calls in the agent app in the same window

    In “Chat and calls” a call no longer opens a separate window: like in Teams it appears at the top of the right-hand area with the chat below; the button at the top right expands it to full height. “Accept” in the agent’s call notification also answers in the app and opens the conversation (from agent 1.0.0.13).

Version 1.0.0.4520 October 2026

  • NewAgent

    Chat and calls as a small app in the agent

    “Chat and calls…” in the agent now opens a slim app just for teams, channels, conversations and calls – without mail and without a browser. You are signed in automatically while the device is paired; every such sign-in is recorded with the device name in the sign-in log. Once you unpair a device under Settings → Devices, it signs nobody in any more (from agent 1.0.0.12).

  • New

    Ringback tone when calling

    When you call someone you now hear the familiar ringback tone (1 second tone, 4 seconds pause) until they answer or decline.

  • New

    Enlarge pictures in a call

    Clicking a picture shows it large and moves the others into a strip; a double-click switches to full screen. Your own picture can be made larger or smaller in four steps, or shown large itself.

  • New

    Share a screen or window

    During a call the new button shares an entire screen, a single window or a tab – with several screens you choose in the system’s picker. This also works in an audio call. On the Mac, macOS asks for screen recording permission the first time.

Version 1.0.0.4420 October 2026

  • New

    Gentle tones and melodies for ringing

    Settings → Calls now offers 15 ringtones in three groups: Ringing, Gentle (new: Harp, Wind chime, Crystal) and Melodies – Für Elise, Ode to Joy, Eine kleine Nachtmusik, Morning Mood, Brahms’ Lullaby, the Westminster chime and Greensleeves. All melodies are in the public domain, generated by sarebamail itself from notes, no recordings. Applies in the browser and in the agent (from agent 1.0.0.11).

  • Fixed

    All ringtones equally loud

    The default tone “Classic” was noticeably quieter than the others. All tones are now matched to the same perceived loudness; “Classic” is about 9 dB louder than before.

  • NewAgent

    Chat and calls in the agent’s own window

    The “Chat and calls…” menu item opens sarebamail in a window of the agent’s own – chat and call without opening the browser. The first time, you sign in there once and confirm camera and microphone once. Links to other sites open in the default browser. On Windows and macOS; on Linux the item opens the browser (from agent 1.0.0.11).

Version 1.0.0.4320 October 2026

  • ImprovedWeb interface

    Overview refreshes itself

    The overview shows without reloading who is online right now and where new chat messages are waiting (every 10 seconds), plus mail counts, appointments and tasks every minute. This only happens while the window is visible, and immediately when you return to the tab.

  • NewAgent

    Missed calls in the agent

    If nobody answers, the agent shows “Missed call from …”, and a red number appears on its icon in the taskbar or menu bar. It disappears as soon as you open sarebamail from the agent. Calls you answered or declined in another window do not count (from agent 1.0.0.10).

  • ImprovedAgent

    Choose the ringtone from the agent

    The “Choose ringtone…” menu item opens Settings → Calls in the browser. The tone chosen there also applies in the agent (from agent 1.0.0.10).

  • FixedAgent

    Ringtone on the Mac, restart after update

    On the Mac the agent rings audibly again when a call comes in – the sound now plays inside the agent itself. After an update it starts the new version before quitting; until now it stayed closed on the Mac afterwards (from agent 1.0.0.10).

Version 1.0.0.4220 October 2026

  • New

    Choose a ringtone

    Settings → Calls offers five ringtones – Classic, Soft, Marimba, Bell and Digital – with preview. The chosen tone applies in the browser and in the sarebamail agent.

  • NewAgent

    Call window with Accept and Decline

    A call shows up in the agent with the caller’s name, a green “Accept” and a red “Decline” button – on the Mac as its own window in front, on Windows as a call notification. “Decline” really declines the call: the caller sees it, and all windows stop ringing (from agent 1.0.0.9).

  • FixedAgent

    Agent update on the Mac

    An older copy of the agent (for example still in the Downloads folder) no longer overwrites the installed newer version but starts it. After an update the agent restarts reliably (from agent 1.0.0.8).

  • FixedWeb interface

    Download shows the newest version right away

    The download page offers a new agent version within a minute of its release and shows the version number prominently at the top and on every download button.

Version 1.0.0.4020 October 2026

  • Improved

    Louder ringtone

    An incoming call rings in the browser and in the agent on the Mac with a clearly audible tone of four short beeps, every two seconds or so.

  • Fixed

    Call stops ringing everywhere

    Once you accept or decline in one place – a browser window or the agent – the other windows and the agent stop ringing.

  • FixedWeb interface

    Calls when the camera is in use

    If another application is using the camera, a video call continues without your own picture instead of failing. A busy or missing microphone gets its own clear message.

  • FixedAgent

    Calls on the Mac

    The agent on macOS stays reachable in the background and rings repeatedly on a call until it is accepted, declined or hung up – even if notifications are turned off in System Settings. If they are off, the agent menu shows “Allow notifications…” (from agent 1.0.0.7).

Version 1.0.0.3819 October 2026

  • FixedWeb interface

    Description under Settings → Plan

    A technical name appeared below the heading instead of the description.

Version 1.0.0.3719 October 2026

  • NewWeb interface

    News and what’s new on the overview

    The overview shows the latest changes to sarebamail and a “News” area with announcements from the operator and current headlines in your language. The server fetches the headlines – the news site learns nothing until you open a link.

  • NewWeb interface

    Plans and limits

    Settings → Plan shows the limits of your account and how many messages you sent today. If your plan does not allow attachments, attaching is disabled when composing; when a limit is reached, sarebamail tells you which one.

Version 1.0.0.3619 October 2026

  • NewWeb interface

    Recurring appointments

    Appointments can repeat daily, weekly, monthly or yearly, also every 2, 3 … days, weeks, months or years, without end or until a date. When editing or deleting a recurring appointment, the calendar asks whether you mean only this one, this and all following, or the whole series.

Version 1.0.0.3519 October 2026

  • NewWeb interface

    Right-click menus everywhere

    Overview, module bar, mail reading pane, chat (conversations, channels, folders, messages, calls), calendar, contacts, tasks, notes, devices and user management offer the actions available there on right-click – such as open, open in new tab, call, quote, new appointment here, priority, colour or delete with confirmation. Ctrl+right-click and input fields keep the browser menu.

Version 1.0.0.3419 October 2026

  • NewWeb interface

    Red counters on the icons on the left

    Mail shows unread messages in your inboxes, Chat unread messages and missed calls, Calendar the appointments still ahead today, Tasks everything due today or overdue.

    And right after waking from sleep. If a newer version cannot be installed automatically, the icon menu says so and a notification links to the download page.

Version 1.0.0.3319 October 2026

  • NewWeb interface
