Hi, I'm already using header_checks (regexp) to reject outgoing mails containing a specific string in the subject. (OK, usually incoming mails don't include this string in the subject).
Now I wanted to reject incoming emails with forged From:-Header containing my own domain. So I attached a new regexp line in the existing header_cheks file in warning mode. But the result is that everything (in- and outbound mails)containing my domain in the From:-Header would be rejected. How can I apply this check to only incoming mails? I'm running postfix 2.7.1 on RHEL 5.6 Thanks for your help J.T.
