Dovecot v2.3.20 released
by Aki Tuomi 22 Dec '22

22 Dec '22

We are pleased to release v2.3.20 of Dovecot. https://dovecot.org/releases/2.3/dovecot-2.3.20.tar.gz https://dovecot.org/releases/2.3/dovecot-2.3.20.tar.gz.sig Binary packages in https://repo.dovecot.org/ Docker images in https://hub.docker.com/r/dovecot/dovecot Regards, Aki Tuomi Open-Xchange oy -- + Add dsync_features=no-header-hashes. When this setting is enabled and one dsync side doesn't support mail GUIDs (i.e. imapc), there is no fallback to using header hashes. Instead, dsync assumes that all mails with identical IMAP UIDs contains the same mail contents. This can significantly improve dsync performance with some IMAP servers that don't support caching Date/Message-ID headers. + lua: HTTP client has more settings now, see https://doc.dovecot.org/admin_manual/lua/#dovecot.http.client + replicator: "doveadm replicator status" command now outputs when the next sync is expected for the user. - LAYOUT=index: duplicate GUIDs were not cleaned out. Also the list recovery was not optimal. - auth: Assert crash would occur when iterating multiple userdb backends. - director: Logging into director using master user with auth_master_user_separator character redirected user to a wrong backend, unless master_user_separator setting was also set to the same value. Merged these into auth_master_user_separator. - dsync: Couldn't always fix folder GUID conflicts automatically with Maildir format. This resulted in replication repeatedly failing with "Remote lost mailbox GUID". - dsync: Failed to migrate INBOX when using namespace prefix=INBOX/, resulting in "Remote lost mailbox GUID" errors. - dsync: INBOX was created too early with namespace prefix=INBOX/, resulting a GUID conflict. This may have been resolved automatically, but not always. - dsync: v2.3.18 regression: Wrong imapc password with dsync caused Panic: file lib-event.c: line 506 (event_pop_global): assertion failed: (event == current_global_event) - imapc: Requesting STATUS for a mailbox with imapc and INDEXPVT configured did not return correct (private) unseen counts. - lib-dict: Process would crash when committing data to redis without dict proxy. - lib-mail: Corrupted cached BODYSTRUCTURE caused panic during FETCH. Fixes: Panic: file message-part-data.c: line 579 (message_part_is_attachment): assertion failed: (data != NULL). v2.3.13 regression. - lib-storage: mail_attribute_dict with dict-sql failed when it tried to lookup empty dict keys. - lib: ioloop-kqueue was missing include breaking some BSD builds. - lua-http: Dovecot Lua HTTP client could not resolve DNS names in mail processes, because it expected "dns-client" socket to exist in the current directory. - oauth2: Using %{oauth2:name} variables could cause useless introspections. - pop3: Sending POP3 command with ':' character caused an assert-crash. v2.3.18 regression. - replicator: Replication queue had various issues, potentially causing replication requests to become stuck. - stats: Invalid Prometheus label names were created with specific
