Hi all,


We receive a lot of spam from "www-data@xxxxx17363"@domain.com so I create a rule like below and works pretty well, but I don't know how to create a variation to block everything that starts with "return-" like [email protected] my ideia is create a variable like %BadSenders but I really don't know how to code that, actually is better point to a file. ($BadSender = /etc/mail/mimedefang-badsenders).


sub filter_sender {
    my ($sender, $ip, $hostname, $helo) = @_;
if ($sender =~ /^<?"www-data\@([A-Z][a-z0-9_.=]*)"\@([A-Z][a-z0-9.-]*)>?$/i) { return ('REJECT', "Reject - http://www.example.com/postmaster.html";);
        }
        return ('CONTINUE', "ok");
        }



Regards,
Ricardson
