Local Packages
Updated dovecot to 2.2.24:
doveconf now warns if it sees a global setting being changed when the same setting was already set inside some filters (a common mistake has been adding more plugins to a global mail_plugins setting after it was already set inside protocol { .. }, which caused the global setting to be ignored for that protocol)
LMTP proxy: Increased default timeout 30s -> 125s, which makes it less likely to reach the timeout and cause duplicate deliveries
LMTP and indexer now append ":suffix" to session IDs to make it unique for the specific user's delivery (fixes duplicate session ID warnings in stats process)
Added dict-ldap for performing read-only LDAP dict lookups
lazy-expunge: All mails can be saved to a single specified mailbox
mailbox { autoexpunge } now supports wildcards in mailbox names
doveadm HTTP API: Added support for proxy commands
imapc: Reconnect when getting disconnected in non-selected state
imapc: Added imapc_features=modseq to access MODSEQs/HIGHESTMODSEQ; this is especially useful for incremental dsync
doveadm auth/user: Auth lookup performs debug logging if -o auth_debug=yes is given to doveadm
Added passdb/userdb { auth_verbose=yes|no } setting
Cassandra: Added user, password, num_threads, connect_timeout and request_timeout settings
doveadm user -e <value>: Print <value> with %variables expanded
Huge header lines could have caused Dovecot to use too much memory (depending on config and used IMAP commands); typically this would result in only the single user's process dying with out of memory due to reaching service { vsz_limit } - not a global DoS
dsync: Detect and handle invalid/stale -s state string better
dsync: Fixed crash caused by specific mailbox renames
auth: Auth cache is now disabled passwd-file; it was unnecessary and it broke %variables in extra fields
fts-tika: Don't crash if it returns 500 error
dict-redis: Fixed timeout handling
SEARCH INTHREAD was crashing
stats: Only a single fifo_listeners was supported, making it impossible to use both auth_stats=yes and mail stats plugin
SSL errors were logged in separate "Stacked error" log lines instead of as part of the disconnection reason
MIME body parser didn't handle properly when a child MIME part's --boundary had the same prefix as the parent
Updated pigeonhole to 0.4.14:
The address test now allows specifying the X-Original-To header
Implemented the Sieve imapsieve extension and its IMAP counterpart (RFC 6785) as a set of plugins, which allows running Sieve scripts at IMAP activity, rather than at delivery
Adjusted the Sieve ihave extension to allow capability tests to be performed at runtime; this way, scripts can be written that work both at delivery and from IMAP
Implemented support for runtime trace debugging, which works much like the Dovecot rawlog facility
Added a "sieve_user_email" setting that configures the user's primary email address; this is mainly useful to have a user email address available in IMAP, where envelope data is unavailable
Implemented the dovecot-specific "vnd.dovecot.report" extension, which allows sending report messages in the Message Abuse Reporting Format (RFC 5965)
extprograms plugin: Fixed epoll() panic caused by closing the output FD before the output stream
- Made sure that the local part of a mail address is encoded properly using quoted string syntax when it is not a dot-atom
