what happens if I put one such thing on my mailserver too and want to send you a mail? My outgoing MX starts a smtp connection, and then, at RCPT TO, your system starts a smtp dialogue with my incoming MX. Unless the machines are tightly coupled, my incoming MX does not expect to get a verification probe - it will believe that you try to send me some mail, and probe your machine. This looks like a source of infinite loops :(
All of the milters are configured with an address verfication address. This is used as the sender when verifying addresses and so when the address is seen in an incoming session it is allowed through.
I use [EMAIL PROTECTED] matt
