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.
