Hello,

I just upgraded my servers from Dovecot 2.1.2 to Dovecot 2.1.3-0~auto+5 by using Debian binaries from "http://xi.rename-it.nl/debian/ stable-auto/dovecot-2.1 main".

The config was not touched but now IMAP connections are not possible anymore (LMTP works fine). When I try to connect to a mailbox, the connect fails.

Some log entries:

The MySQL authentification seems to work fine, but after this the connection is closed with the SSL alert. In Dovecot 2.1.2 everything worked fine. The SSL certifcate is also correct.

Any hints are welcome to identify the problem. Thanks in advance.
