- update to 2.3.19 and pigeonhole 0.5.19
Dovecot 2.3.19
+ Added mail_user_session_finished event, which is emitted when the mail
user session is finished (e.g. imap, pop3, lmtp). It also includes
fields with some process statistics information.
See https://doc.dovecot.org/admin_manual/list_of_events/ for more
information.
+ Added process_shutdown_filter setting. When an event matches the filter,
the process will be shutdown after the current connection(s) have
finished. This is intended to reduce memory usage of long-running imap
processes that keep a lot of memory allocated instead of freeing it to
the OS.
+ auth: Add cache hit indicator to auth passdb/userdb finished events.
See https://doc.dovecot.org/admin_manual/list_of_events/ for more
information.
+ doveadm deduplicate: Performance is improved significantly.
+ imapc: COPY commands were sent one mail at a time to the remote IMAP
server. Now the copying is buffered, so multiple mails can be copied
with a single COPY command.
+ lib-lua: Add a Lua interface to Dovecot's HTTP client library. See
https://doc.dovecot.org/admin_manual/lua/ for more information.
- auth: Cache lookup would use incorrect cache key after username change.
- auth: Improve handling unexpected LDAP connection errors/hangs.
Try to fix up these cases by reconnecting to the LDAP server and
aborting LDAP requests earlier.
- auth: Process crashed if userdb iteration was attempted while auth-workers
were already full handling auth requests.
- auth: db-oauth2: Using %{oauth2:name} variables caused unnecessary
introspection requests.
- dict: Timeouts may have been leaked at deinit.
