Dear Enrico,

I've a Debian 11 mail server with Postfix 3.5.25. I've configured Postfix to filter the headers with: header_checks = pcre:/etc/ postfix/header_checks.pcre However, some emails with subjects listed in the file are still delivered. E.g.> /^Subject:.*Pulitore.WC.Più.Votato.2025.*/ REJECT A positive test result: postmap -q "Subject: Pulitore WC Più Votato 2025" pcre:/etc/postfix/header_checks.pcre REJECT Why Postfix don't reject the email? Where I've to investigate? After writing a new entry in header_checks.pre, have I to reload Postfix?
Please look at and share the actual header entry Subject in the emails. Often they are encoded, and Postfix header checks don’t decode it. You need to use a milter for this usecase.
Kind regards, Paul _______________________________________________ Postfix-users mailing list -- [email protected] To unsubscribe send an email to [email protected]
