Adding the Precedence: Bulk header is a good idea.

Another thing you can try is MIMEDefang 2.26-BETA-1, available at
http://www.roaringpenguin.com/mimedefang/#download

It has an experimental function called md_check_against_smtp_server.
You can do this in your filter_recipient function:

sub filter_recipient
{
    my($recip, $sender, $ip, $host, $first, $helo) = @_;
    return md_check_against_smtp_server($sender, $recip,
					"mimedefang.host.name",
					"real-mail-server.host.name");
}

If the real mail server would reject the recipient at the RCPT TO: phase,
so does MIMEDefang.

Watch out... this may increase the load on your real mail server, and it
will create a lot of annoying log entries because of the RCPT TO: probes.
But it might be a good solution for some people.

Regards,

David.
