Hi everyone,
I'm not sure if I'm missing something but I can't find out why my
body_checks doesn't catch all the backscatter I'm getting right now.
I've it configured like this:
root@alita:/etc/postfix# postconf -n body_checks
body_checks = pcre:$config_directory/body_checks.pcre
root@alita:/etc/postfix# cat body_checks.pcre
/^[> ]*Message-ID:.*@(fire-world\.de)/
reject SPAM backscatter with forged domain name in Message-ID header
One example it doesn't catch seems to match the regex when I test it
manually:
root@alita:/etc/postfix# postmap -q - regexp:/etc/postfix/body_checks.pcre
<backscatter.txt
Message-ID: <aaa3ea41b5715b55f65c128bef2a60211...@fire-world.de> reject
SPAM backscatter with forged domain name in Message-ID header
I've got the original message (from my mailbox) here for you:
https://www.karotte.org/big/backscatter.txt
As I said, Postfix rejects some of the backscatter but not all. Any
idea why it didn't reject this?
Best Regards
Sebastian
