Could some one recommend a good Software for me in these two categories available for OpenBSD? Is there any good reason why a decent mailer daemon will not work? Almost all offer some sort of content filter, to which you can add your own hooks. As to the second part, I don't know. If you can control incoming/outgoing mail (via SMTP), I do not see the point of checking POP as well, either. Joachim

Re: Good SMTP and POP proxy for OpenBSD
Smtp proxy? You mean an emailserver. I have postfix running as my primary mailserver. It delivers mail to my backend Exchange server and relays e-mail voor the same exchange server. So, in a way, it's proxy-ing the e-mail. With postfix, you have almost unlimited control over the complete mail process. I thought stunnel could also proxy encrypted pop3 traffic.

Thankyou so much :-) Kind Regards Siju Siju, We've implemented, on a few small scale installations, Postfix on the firewall which simply does a few Spam checks and passes it on to the real mail server. Never had any problems, and makes me feel better since I can't fully trust my internal mail server. Happy days, Bill
