I put in the usual header checks:-

header_checks = regexp:/etc/postfix/header_checks

added -v to my cleanup (master.cf). Reloaded postfix and sent an email to
myself as a test, output shown below:-

postfix/cleanup[31260]: maps_find: regexp:/etc/postfix/header_checks:
Subject: Why no reject Brutal Gun Rapes = REJECT

Yet postfix didn't refuse the email as shown above? any ideas why not?


Cheers,

Pete
