[Dovecot] SSL Certificate Anomalies with latest code changes

Some change between bf5ae73e9475 and 584bd77c38fd seems to have broken something in the SSL Handshake. A previously valid server certificate is deemed invalid by various mail clients.

http://hg.dovecot.org/dovecot-2.1/rev/bf5ae73e9475 works fine while http://hg.dovecot.org/dovecot-2.1/rev/584bd77c38fd does not.
