Changelog published on October 1st 2026​

BlueMind Webmail (Mail App)​

  • BM-22778: Fixes: Searching for emails using wildcards (*) now works correctly.
  • BM-23642: Fixes: Deleting an attachment whilst forwarding an email causes the “...” button, used to expand the conversation, to disappear.
  • BM-23774: Fixes: Displays the original creation date of the draft instead of the actual send date on a sent email.
  • BM-24252: Fixes: Resizing the window causes the "..." button used to expand the conversation to disappear.
  • Fixes: A pop-up window would remain stuck at the edge of the screen next to a wide element.
  • Fixes: The search for delegates incorrectly included the user themselves and their already configured delegates in the suggestions.

Preferences​

  • Fixes: Inability to have more than one out-of-office or forwarding rule active per mailbox.

BlueMind thick client (Electron)​

  • BM-23976: Fixes: When the network context changes, if the BlueMind client (Electron) is not restarted (and remains open), emails may no longer be sent, with a draft becoming stuck in a state where it cannot be saved, thereby preventing all other drafts from being saved.

MAPI / Outlook​

  • BM-21721: Fixes: Loss of organizer on single appointment.
  • BM-23321: Fixes: Duplicate entries in the mapping of properties named ‘Outlook’ (pidmapping), which could prevent the installation upgrade from completing.
  • BM-24004: Fixes: Loss of an email saved in .msg format when dragged and dropped onto an appointment in Outlook.
  • BM-24250: Fixes: Confirming a calendar event causes the event to disappear in Outlook.
  • Fixes: Inability to attach a file that has already been attached to an event when the user does not have the permission to link files, and the removal of existing attachments from the event.
  • Fixes: A meeting may end up with no organiser or participants when Outlook sends a meeting request without an username.
  • Fixes: A contact search in the global directory could, for example due to a typo in an address, return all records in the domain, causing significant slowdowns in Outlook.
  • Improved reliability and performance of searches in the Global Address List (GAL) from Outlook during periods of high concurrent usage.

Mobile Devices (EAS)​

  • BM-24255: Fixes: Outlook mobile clients freeze during folder configuration and synchronisation.

Thunderbird​

  • BM-24223: Correction to the title of the BlueMind Preferences tab.

Video Conferencing​

  • Built-in integration of the Nextcloud Talk videoconferencing provider.
  • BM-24293: Fixes: Removal of the Pexip session associated with an event when that event is deleted.

Administration / Architecture​

Administration console​

  • BM-23010:
    • Feature: The mail app management tab for a user or a shared mailbox now allows you to manage delegations for that user or mailbox.
    • Fixes:
      • A delegation rule could be lost or confused with the out-of-office/redirection rule
      • An obsolete calendar sharing right persisted after a delegation was deleted
  • BM-24236: Fixes:
    • Calendar settings tab missing from the shared mailboxes management page
    • “Access denied” error when publishing the calendar URL for a shared mailbox
  • BM-24181: Fixes: After a password change in AD, the old password is not immediately invalidated for logging into the BlueMind online app.

Clone​

  • Several reliability fixes for server cloning that could have led to data loss or a complete system freeze: user settings and mailbox upgrades entered prior to the directory migration not being restored; organizational units or groups deleted but mistakenly recreated; and the decision to clone the directory being made on the wrong server (in which case the directory was not restored by either of the two streams).
  • Fixes: deadlocks and data corruption related to concurrent access during restoration (directory restoration pipeline, cloning status file potentially becoming unreadable and preventing recovery, orphan and starvation handlers).
  • Fixes: cloning no longer fails when a folder has an empty name (a random name is assigned; a subsequent save renames it).
  • Note: Concurrent restoration of the directory via the dir topic is temporarily disabled. The directory is restored from the domain topic, as was the case prior to migration.

core​

  • BM-24040: Fix: Address books, calendars, to-do lists and notes linked to a shared mailbox are now correctly synchronised with that mailbox’s permissions: a user can no longer inadvertently reduce their own sharing rights on these items.

Email filtering (Milter)​

  • BM-23959: Fixes: An email sent from Outlook by a delegate (on behalf of) is rejected by certain external servers.
  • BM-24229: Fixes: Delivery receipts are not delivered when journaling is enabled

Server upgrade​

  • BM-24132: Fixed the major upgrade script, which now performs a checkpoint before stopping the service.
  • BM-24246: Fixed an API key upgrade task that could be skipped on certain installations.

Upgrade (Keycloak / authentication)​

  • BM-24234: Fixes: A single domain failure halts the entire Keycloak upgrade.

Backup and Restore (DataProtect)​

  • BM-24254: Fixes: Saving email content (SDS) is blocked following the replacement or renaming of a mail server.

Security​

  • (Critical): Sorting of emails and conversations now only accepts known columns. An unknown column is rejected with the error INVALID_PARAMETER.
  • (High): the resolution of external entities and DTDs is disabled in the XML parsers of the DAV server (CalDAV/CardDAV), in net.bluemind.utils.DOMUtils (CAS, MAPI), in the MAPI tags and in the BigBlueButton client.
  • (Critical): Queries on scheduled jobs pass the domain as a bound parameter. A domain administrator can now only see runs within their own domain.
  • (Medium): The directory (AD/LDAP) password cache is cleared every time a password is changed in BlueMind. It now stores an HMAC hash instead of the plaintext password. Its duration can be set using core.security.directory-password-cache-ttl (maximum 20 minutes). (BM-24181)
  • (Medium): The BM* identity headers sent by the client are removed before processing.
  • (Hardening): requests for file sharing and password expiry now use related parameters.
  • Upgrades:
    • PostgreSQL 18.6
    • bm-JDK 25.0.4.1 (with fix for the update-alternatives configuration)
    • Netty 4.1.138
    • Tika 3.3.2
    • Vert.x 4.5.34
