Many under-the-hood changes since Foobruary updates.

Important changes

  • Updated on March 10, 2019: Due to changes in Solr, you should trigger a rescan (not a full reindex!) for all users: docker-compose exec dovecot-mailcow doveadm fts rescan -A – yes, again – sorry!
  • TLSv1.2 is now the min. required protocol for mandatory encryption in Postfix.
    This affects per-user TLS encryption (when a user enforces TLS) or any TLS policy created with “encrypt” policy or higher.
    We only make an exception for authenticated connections over port 587 and 465, where we accept TLSv1 and higher.
    Dovecot remains at TLSv1+ for IMAP, while we require TLSv1.2+ for LMTP connections now.
  • “vacation-seconds” can now be used in sieve filters
  • The IPv6 NAT check in watchdog-mailcow is less CPU intensive
  • A Postfix transport destination “*” now excludes hosts matching /localhost$/
  • Rspamd settings map is checked for changes instead of always re-applying it in Rspamd – saves CPU time
