Blacklist enhancement

It would be ideal if a blacklist would also check and block the email if the blacklisted sender is in the reply-to.

Allot of spam emails use the same reply-to address but will have different from addresses.

    Reply-To is a mail header and not available to Postfix policy server (e.g. iRedAPD), so cannot blacklist it with iRedAPD. You need a content filter like SpamAssassin to do this. For example:

    header my_custom_spam Reply-To =~ /
    score  my_custom_spam 100
