Hi again, I need to tell postfix to force smtp only for certain senders.
I read http://www.postfix.org/TLS_README.html which helps me get tls running w/ postfix, plus "Client TLS limitations". I'm thinking of using smtpd with smtpd_tls_wrappermode=yes on a different port. But my main problem is stopping those senders from using the regular smtp. Any ideas on how to best achieve this. Regards, mlistus
