Gromox 3.1

Enhancements:

• http: support for SPNEGO authentication (Kerberos-in-SPNEGO or NTLMSSP-in-SPNEGO)
  with the HTTP "Authorization: Negotiate" header.
• dscli: try all oxdisco URLs until one succeeds
• exmdb: support repeated import of permission data (e.g. from kdb2mt)
• ews: create calendar item after accepting a MR with MacMail

Fixes:

• emsmdb: the total mail count in a contents view was not updated
• emsmdb,zcore: Send-As mail now correctly has the delegator in Envelope-From
• email_lib: deal with MIME parts with zero header lines
• tools: reinstate submit.php for delayed sending
• nsp: avoid buffer overruns in nsp_interface_fetch_property
• emsmdb: Partial message change tracking was bug-ridden and deleted. Standard transfers are now used instead. (E.g. an IPM.Task object where only the percentage-completed field was changed would be mis-synchronized to another Cached Mode client as "delete start/end dates".)
• exmdb: Public folders were missing timeindex queries and their content tables might have shown fewer messages.
• http: A workaround was added for OpenSSL 3.0 so that connections from Outlook 2010 once again succeed.
• mysql_adaptor: Improve the time needed to compute the composite mailbox permission for user in a case of a mailbox with 100K ACL entries.

Changes:

• exmdb: deactivate movecopy/deletemessages event storm compaction
• emsmdb: outgoing lzxpress compression in the EMSMDB protocol is now disabled as it does not compress well for the time invested.
• http: the ntlm_program_helper config directive was removed; your gss_program simply needs to handle both GSS and NTLM.
• event: support for reading the old event_acl.txt was deleted. The replacement is the event_hosts_allow config directive.
• timer: support for reading the old timer_acl.txt was deleted. The replacement is the timer_hosts_allow config directive.

Gromox 3.0

Enhancements:

• eml2mt now transmits the RFC5322 representation into the message store so that IMAP clients can serve that instead of representation synthesized from MAPI data. / Messages imported via eml2mt no longer "lose" their original structure and headers when viewed in IMAP.
• midb now transmits the RFC5322 representations of messages created via IMAP into the message store. (Previously: just into the midb cache.) / Messages which have been client-side copied in IMAP, i.e. with FETCH+STORE rather than COPY, no longer "lose" their structure and headers.
• oxcical: implement support for VTODO and VJOURNAL
• mbop: add "freeze" and "thaw" commands
• mbop: support UTC/zone suffixes for getfreebusy -a/-b arguments
• mbop: using the -v option will now additionaly report the mailbox and subcommand in error messages
• exmdb: new config directive exmdb_eph_prefix to put ephmeral files like tables.sqlite3 on a local disk (in case a mailbox is regularly on NFS).
• exmdb: add a time index over messages to speed up common cases of grommunio-web GetContentsTable requests.
• exmdb: the derivation for the PR_MESSAGE_*_ME property value, upon delivery, now includes PR_EMAIL_ADDRESS as a fallback if PR_SMTP_ADDRESS is unset.
• oxdisco: the AutoConfig mechanism now emits an EWS server information block
• ews: include ParentFolderId in FindFolder/GetFolder response
• ews: implemented GetDelegate, CreateAttachment, FindPeople (GAL lookup), PushSubscriptionRequest request handlers
• ews: implemented oofReply responses like EX/365
• ews: Direct Meeting Response related serialization was added
• ews: referenced calendar items are now updated when a CreateItem request contains AcceptItem or DeclineItem tags.
• ews: support GetUserAvailabilityRequest request TimeZoneContext tag.
• zcore: Out of Office configuration reading and writing is now performed over the network rather than through direct filesystem access.

Fixes:

• fnevObjectCreate event notifications were not created when a mail was processed through TWOSTEP Rule Processor, now fixed.
• fnevObjectCreated event notifications were not created when a mail was processed by ONESTEP Rule Processor when that executed a OP_COPY operation.
• oxcical: iCal events with a date in DTSTART & DTEND but without X-MICROSOFT-CDO-ALLDAYEVENT are now transformed into Allday events even if the event is longer than one day.
• delivery: emit MDN-RRT messages even with lda_twostep_ruleproc is set.
• oxdisco: config-v1.1.xml now contains the homeservers as it should.
• oxdisco: AutoConfig XML now features the incomingServer type parameter in the right place.
• oxdisco: AutoConfig now emits outgoing server port 587 as type smtp.
• ruleproc: auto-enter MRs into target calender even if the sender is not going to get a response.
• ews: Avoid sending multiple <?xml ?> lines into the notification stream HTTP response body.
• ews: trim "duplicate" recipients when a newly-created item has recipients in both <mimeContent> and <To>/<Cc>.
• ews: prevent FAI messages from polluting the Normal Message Set during ICS
• ews: when the FindItem requests finds no objects, an empty RootFolder tag is now still returned.
• ews: delete excess NUL byte from tCalendarItem:UID tags

Changes:

• kdb2mt no longer imports LocalFreebusy control messages, since dangling references in those can make delegate permission editing via OL nonfunctional.
• emsmdb: outgoing lzxpress compression in the EMSMDB protocol is now disabled as it does not compress well for the time invested.

Enhancements:

• gromox.cfg now has a ruleproc_debug directive (applies to the TWOSTEP Processor only)

Fixes:

• ews: repair a nullptr dereference from the OOF XML change

• HTML-to-Text conversion using w3m suffered from an encoding mismatch, which was fixed.

Changes:

• oxcmail: upon ingestion, the Precedence header (RFC 2076) is now transformed to the MAPI property PR_INTERNET_PRECEDENCE.
• exmdb_local: Out-of-office autoreply logic now recognizes PR_INTERNET_PRECEDENCE values bulk and list to inhibit certain and all responses, respectively.
