Hi, I recently had some monit alerts on a server when I updated to the latest dovecot version 2.2.13 (no such problem with 2.2.9).
The monit config lines are these: check host milch-mailserver with address milch.schokokeks.org if failed host milch.schokokeks.org port 993 type tcpssl sslauto protocol imap for 5 cycles then alert I get [CEST Jun 15 16:59:20] debug : 'milch-mailserver' succeeded connecting to INET[milch.schokokeks.org:993] via TCPSSL [CEST Jun 15 16:59:20] error : 'milch-mailserver' failed protocol test [IMAP] at INET[milch.schokokeks.org:993] via TCPSSL -- IMAP: error receiving data -- Success It seems dovecot itself is up and running, this seems to be a monit problem to me. The configuration line above is the example from the monit wiki, so it should work. This only happens for the ssl-ports. If anyone needs to do tests on our server milch.schokokeks.org feel free to do so (but I may decide to go back to the older dovecot version when I can't resolve this issue soon). Dovecot 2.2.13 introduces some new protection against DoS-attacks on SSL [1], I assume it may have something to do with that. Any help apprechiated.
