BM-22599: Fixes: Unable to post to a group containing only a subgroup without an email address.
BM-23388: Fixes: An invitation in a single-part email (where the email itself has a Content-Type of text/calendar) is not processed.
BM-23608: Fixes: The frequency bonus in the address suggestion weighting is not taken into account.
BM-23699: Fixes: Error in the logs when expanding or collapsing a folder tree.
BM-23764: Fixes: In some cases, changes to an appointment's date and time are not applied.
BM-23840: Fixes: Emails with very long subject lines cause a database processing error in the conversation view.
BM-23844: Fixes: Error when previewing EML-format attachments.
BM-23857: Fixes: When a first name followed by an 'R' is entered in the recipient field, the results are prefixed with "rong >".
BM-23877: Fixes: Inconsistency in the results displayed when using the "read" or "not deleted" system filters (filters that exclude emails from the trash's double-bottom from search results).
BM-23937: Fixes: Failed to create a filter from an email because the sender field was single-valued instead of multivalued.
BM-23803: Fixes: When sending a quick reply (SmartReply) to an email in which only one recipient is invalid (does not exist or has been deleted), the non-delivery notification is not received, and the email remains in the Outbox with an error status, even though it is successfully delivered to the valid recipients.
BM-23897: Fixes: A blocking call on the server's event loop during the processing of Ping commands could degrade the responsiveness of all mobile connections.
BM-23912: Fixes: Description is lost when editing a recurrence exception.
Fix: A single device can no longer open multiple simultaneous push orders, which prevents unnecessary server-side resource consumption.
BM-23869: Fixes: Outlook synchronization freezes when marking an email as read or unread.
BM-23902: Fixes: The offline address book (OAB) client cache was not working properly; each client was re-downloading the entire OAB. The cache is now being used correctly, and download errors are being reported.
BM-23903: Fixes: Incorrect and overly verbose logs when decoding MAPI responses, for more reliable diagnostics.
Fixed several internal errors (NullPointerException when notifying about a deleted email, conversion errors related to folder properties) that could interrupt synchronization.
Improved robustness and performance for large-scale Outlook synchronizations (during migrations): timeouts, cache sizes, and other internal parameters are now adjustable settings; the address book cache has been expanded to reduce the load on keydb; email bodies are read directly from object storage; and query processing makes better use of virtual threads.
BM-23824: New mail repair-orphaned-folder command to repair folders whose mbox_records container is missing from the database.
BM-23889: Fixes: The mail delete-message command does not use the required quotes for the parameters.
New group size command that calculates the total size of the mailboxes of a group's members; the command returns the sum of the members' mailboxes and the mailboxes to which they are subscribed.
New mapi-sync-monitor command to monitor MAPI synchronization.
BM-23244 Added an Outlook compatibility warning to the shared mailbox sharing preferences: only the sharing rights "Can update the shared mailbox and manage sharing" and "All rights on the shared mailbox" allow access from Outlook. ↳ For further information seeEditing shared mailboxes > Sharing and delegation.
BM-23451: Fixes: The dates in automatic replies set in Outlook are not displayed correctly.
BM-23834: Fixes: The tab for adding an email filter is labeled "Edit a filter."
BM-23848: Fixes: Inconsistency in sharing rights between the administration console and the user interfaces.
BM-23808 Fix: Improved reliability of non-delivery reports ("NDR" emails) regardless of the originating client (webmail, Outlook, mobile): Fixed errors that prevented the report from being sent or caused it to fail. Add a Message-ID header if it is missing from the email.
BM-23815: Fixes: Failure to delete a mail app folder when associated containers are missing from the database.
BM-23835: Fixes: Infinite loop with error stack in the logs when processing a delayed send scheduled by a deleted user.
BM-23861: Fixes: The original email attached to the non-delivery report may cause the delivery process to fail.
BM-23880: Fixes: Improved reliability of message processing for resources.
BM-23885: Fixes: When a resource does not have a designated manager, the meeting organizer receives a delivery failure error that does not include text explaining the error.
The limit on the number of recipients for an email has been increased to 2,000.
BM-23606: Fix: Correct queuing of elements in Vert.x contexts when using a Vert.x client of type BufferedStream / Async (used in EAS). This prevents Vert.x code from being executed from non-Vert.x threads.
BM-23882: Fixes: Off-heap memory leaks in the construction of MIME emails by the Outlook connector.
BM-23883: Fixes: Fixed an off-heap memory leak in the LMTP resend pipeline.
BM-23895: Fixes: Off-heap memory leaks identified during the processing of email bodies (webmail, EAS, MAPI, internal feeds).
BM-23901: Fixes: REST Feed: Fixed a scheduling bug (LIFO instead of FIFO) that could corrupt transferred streams.
Fixed a potential JVM crash (segfault) that could occur when emptying the webmail outbox.
BM-21978: Fixes: Deleting a resource no longer leaves orphaned containers in the database.
BM-22585: Added the ability to enable unsecured S3 connections via the command line.
BM-23794: Fixes: Failure of the hotupgradedelete-drafts-outbox-indexed-docs when subtree containers are missing.
BM-23799: Fixes: Cloning could delete the external username assigned to a directory entry; email identities created prior to version 5.5.11 are also ignored when restoring a clone.
BM-23805: Fixes: After deleting and recreating an account, the account can no longer send emails, neither internal nor external.
↳ Fix for the milter directory cache: the Sender header added during a "send on behalf" send contained a guessed address instead of the actual mailbox address, and invalidating the cache was resource-intensive and could leave entries out of date.
Fix: Reduces the verbosity level of the KafkaTopicStore startup log to debug.
On systems that do not have either Kafka or ZK installed, this caused a false warning: kafka.bootstrap null, zk null.
Fix: The function to clear the outbox is now resilient to failures of leadership().
BM-23934: Fixes: Failures of the updateByQuery command on a mailspool index caused the mandatory task to remain marked as SUCCESS even though the remaining indexes were only partially populated.
The error is now rethrown so that the task fails and is retried, and a complete execution now ends with monitor.end(true).
BM-23935: Fix: Check for the existence of emails in the Object Store in addition to the database when migrating the Cyrus spool.
Nginx load balancing now uses a round-robin policy instead of ip_hash to ensure better distribution of connections.
