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.
