I'll assume your content_filter reinjects mail to localhost:10025 after processing. Note: make sure your post-filter header checks don't ever reject mail. That would make you a backscatter source and get you blacklisted. The cleanest way to do this is a separate postfix instance (not just a master.cf listener service) that listens on 10025, with its own header_checks. This also gives the very nice benefit of separation between pre-filter and post-filter mail. http://www.postfix.org/MULTI_INSTANCE_README.html Alternately, you can do some master.cf gyrations. This is likely easier to set up, but more confusing long-term. Something like: # master.cf # existing reinjection listener 127.0.0.1:10025 inet n - n - - smtpd ... existing stuff ... -o cleanup_service_name=cleanup_filter # copy of the existing cleanup service cleanup_filter unix n - n - 0 cleanup -o header_checks=pcre:/etc/postfix/header_checks_filter -o body_checks= and then put your after-filter checks in header_checks_filter. -- Noel Jones
