Hi folks, Sorry in advance if it's well known matter.
I have some troubles about nested_header_checks in main.cf of postfix. [environment] - OS Solaris10sparc - postfix mail_version = 2.4.6 % postconf header_checks header_checks = regexp:/etc/postfix/header_checks % postconf nested_header_checks nested_header_checks = regexp:/etc/postfix/backscatter_checks % postconf mime_header_checks mime_header_checks = regexp:/etc/postfix/backscatter_checks % cat backscatter_checks /^From: +([^<]+)?<[EMAIL PROTECTED]>$/ REDIRECT [EMAIL PROTECTED] /^Return-path: +<(foo|bar|hoge|fuga)@example\.com>$/ REDIRECT [EMAIL PROTECTED] /^Subject: +Majordomo +results:/ REDIRECT [EMAIL PROTECTED] It's rules against backscatters. In other times, I tried more complicated rules using [if.. (nest nest ...) .. endif ], but there was something wrong, so I decided to make more simple rules at first, then I wrote above rules. But some mails which should be caught by nested_header_checks or mime_header_checks can't help but go through my filter for some reason. And I don't know why.. However, I found a difference between mails which my filter could catch and mails which my filter couldn't. It is the difference whether attached mail has body or not(header only). This is nested_header_checks' feature, right? When I use body_checks, there is no probrem. But it might cause unintended matching. Any information would be appreciated. thanks, isobetti
