[Mimedefang] Question about my filter/header

[Lavoie,Alain [CMC]]

Hi guys!

     I implement in filter_recipient the check to block spam who spoof
the helo define in the How-To.
http://www.mimedefang.org/node.php?id=18   The only modification I added
is the addition of the sender.

    my $x = 0;
    if($helo =~ /(^|.)my.domain$/i)   { $x = 1; }
    if($sender =~ /(^|.)my.domain$/i)   { $x = 1; }

    if($x == 1)
    {
       if($ip !~ /^(1\.2\.|4\.5\.|3\.3\.|9\.12\.)/)
       {
           return("REJECT", "Connection rejected");
       }
    }

The check is working great but sometimes I received spam from my domain.
I check the headers and
the Return-Path: is from my domain. Maybe I'm wrong but this header is
from the mail from: command!?!
I don't know why those spams are passing through with this header... is
there someone who have an idea?


	Thanks a lot!
