I already tried that,  it works but in the logs I see that a milter discard
action is triggered but the mails are delivered.

Then some users reported that it brakes outgoing mails , no headers almost
, everything converted to plain text etc. Unfortunately I this is on alive
That was working with postfix/mailscanner for more than ten years now.
I was forced to stop using mailscanner as the hold portion of the system
was used to flood the machine with backscatter messages, the only way to
stop it was this
and add rules in the header_checks file (and body).

The previous setup was working ok but I don't want to risk getting into the
same situation again.
