(Get the code!)
Port 25 is probably handled by postfix, exim, or sendmail, not dovecot. In any event, you can't simply connect directly to SMTP with TLS; SMTP requires using the STARTTLS command to upgrade a connection to TLS.
I suspect you'll find similar issues with your other ports; I don't know the details of those off-hand as well as SMTP, so I'll just ask how confident you are that your test case accurately reflects the protocols you're trying to test.
Thanks
