I want to create a new debian Linux based postfix system to sit in front
of Exchange 2003 and act only as an SMTP gateway for starters and
possibly do some filtering down the road. There seems to be less than
65,000 connections per day coming at Exchange and I'm thinking to start

Hello list,
When building out the various checks available to postfix, is there a
mechanism for doing a REJECT, WARN or OK plus the reason, en mass,
without pasting the same text a lot? For example...
bad.guy01.com REJECT 550 Reason1
bad.guy02.com REJECT 550 Reason1

You should be able to configure things to allow access only from the
Exchange server and the certificate you configure on it. That is until
those untrusted people rummage around and steal

Luckily I'm not your auditor, have no idea what standards you're trying
to meet, and so YMMV.

Hello,
I have disabled port 587/465 to be accessed publicly.
but port 25 must be open to internet for MTA communications.
My question is, can external users access port 25 for smtp auth and send
