This is a virtual user setup using the Virtual Users And Domains With Postfix, Courier And MySQL (Debian Etch) HowTo Is it possible to run an internal header_check on mail reinjected into postfix "after" amavis scanning? I have a header_check regex file that tests out okay but when trying to run it after reinjection nothing seems to happen. In my postfix master.cf, under the: 127.0.0.1:10025 inet n - - - - smtpd I've added: -o header_checks=regexp:/etc/postfix/header_check.regexp and also removed the no_header_body_checks entry in -o receive_override_options= Is this the wrong way to do it to get header checks after reijection?
