http://dovecot.org/releases/2.2/dovecot-2.2.25.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.25.tar.gz.sig Some minor fixes and (mainly logging) improvements since rc1. * lmtp: Start tracking lmtp_user_concurrency_limit and reject already at RCPT TO stage. This avoids MTA unnecessarily completing DATA only to get an error. * doveadm: Previously only mail settings were read from protocol doveadm { .. } section. Now all settings are. + quota: Added quota_over_flag_lazy_check setting. It avoids checking quota_over_flag always at startup. Instead it's checked only when quota is being read for some other purpose. + auth: Added a new auth policy service: http://wiki2.dovecot.org/Authentication/Policy + auth: Added PBKDF2 password scheme + auth: Added %{auth_user}, %{auth_username} and %{auth_domain} + auth: Added ":remove" suffix to extra field names to remove them. + auth: Added "delay_until=<timestamp>[+<max random secs>]" passdb extra field. The auth will wait until <timestamp> and optionally some randomness and then return success. + dict proxy: Added idle_msecs=<n> parameter. Support async operations. + Performance improvements for handling large mailboxes. + Added lib-dcrypt API for providing cryptographic functions. + Added "doveadm mailbox update" command + imap commands' output now includes timing spent on the "syncing" stage if it's larger than 0. + cassandra: Added metrics=<path> to connect setting to output internal statistics in JSON format every second to <path>. + doveadm mailbox delete: Added -e parameter to delete only empty mailboxes. Added --unsafe option to quickly delete a mailbox, bypassing lazy_expunge and quota plugins. + doveadm user & auth cache flush are now available via doveadm-server. + doveadm service stop <services> will stop specified services while leaving the rest of Dovecot running. + quota optimization: Avoid reading mail sizes for backends which don't need them (count, fs, dirsize) + Added mailbox { autoexpunge_max_mails=<n> } setting. + Added welcome plugin: http://wiki2.dovecot.org/Plugins/Welcome + fts: Added fts_autoindex_exclude setting. - v2.2.24's MIME parser was assert-crashing on mails having truncated MIME headers. - auth: With multiple userdbs the final success/failure result wasn't always correct. The last userdb's result was always used. - doveadm backup was sometimes deleting entire mailboxes unnecessarily. - doveadm: Command -parameters weren't being sent to doveadm-server. - If dovecot.index read failed e.g. because mmap() reached VSZ limit, an empty index could have been opened instead, corrupting the mailbox state. - imapc: Fixed EXPUNGE handling when imapc_features didn't have modseq. - lazy-expunge: Fixed a crash when copying failed. Various other fixes. - fts-lucene: Fixed crash on index rescan. - auth_stats=yes produced broken output - dict-ldap: Various fixes - dict-sql: NULL values crashed. Now they're treated as "not found".
