After a hint from Chris I did some digging on configuring Postfix to listen on a TLS-only port. I found the following information on configuring main.cf and master.cf for TLS in Postfix
Bingo!
'grep smtps /etc/services'
smtps 465/tcp # SMTP over SSL (TLS)
master.cf:
smtps inet n - n - - smtpd
-o smtpd_tls_wrappermode=yes
-o smtp_host_lookup=dns
-o smtpd_sender_restrictions=permit_sasl_authenticated,rejectWorks for [EMAIL PROTECTED] with SASL digest-md5 auth. The main point is, that users logged into SQM can now only relay under their login name (authentication with uid and mail attributes) is hauled out of the local_recipient_maps LDAP record).
Renewed thanks to you all!

Do not CC me or your mail will probably be rejected. I don't like this, either. Blame it on Swen and a slow Internet connection.
