This is my simple solution. M$-Exchange will not generate an NDR if the
message has precedence bulk.

if ($hits >= 15)
{
return action_bounce("We don't accept SPAM");
}
action_change_header("Subject", "***SPAM*** $Subject ($score)");
action_change_header("X-Spam-Score", "$hits ($score) $names");
action_add_header("Precedence", "bulk");
