Does Squirrelmail try to use STARTTLS? Having full session traffic logs
of when Squirrelmail is logging into Dovecot proxy and when logging into
Cyrus proxy would be helpful (ngrep, wireshark, etc). If Squirrelmail
uses STARTTLS, this doesn't really work though (but at least the logs
will reveal that it is doing STARTTLS). Also if it is doing that,
perhaps the issue is SASL PLAIN after all, since Dovecot proxy won't do
STARTTLS to the Cyrus.

Also if you set auth_debug=yes, what do you see in Dovecot logs when
attempting to log in?
