I am using the steps found on the knowledge base to filter spam, foward it to a dummy domain, and send the sender a return message that his email was rejected. Everything works fine except that the sender recieves 2 messages. One with my message about the why his email was rejected and the other is his bounced message with the following message in it:
Invalid final delivery userid: spamabuse-NUL@localhost How do I prevent this second message from going out? thanks, Nelson Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
