This is not the test morrison has suggested. Doing his test with telnet and thus not complete the SSL handshake, the connection stays open much longer than 3 Minutes. I closed the connection now manually after a little more than 2 hours. This is on Dovecot 2.1.7. same here with dovecot-2.2.10
$ date; telnet imaphost 143 Di 14. Jan 21:57:59 CET 2014 <IMAP dialog> . starttls . OK Begin TLS negotiation now.
... now it's 23:53 ant the tcp connection is still established.
in contrast: postfix-2.11 $ date; telnet mx 25; date Di 14. Jan 23:42:45 CET 2014 <SMTP dialog> ... starttls 220 2.0.0 Ready to start TLS Connection closed by foreign host. Di 14. Jan 23:48:10 CET 2014
looks like postfix handle the timeout smarter.
