This check the envelope sender, correct? The Return-path: is an external address. Its the From: in the message header i am battling with. I assume its a header_check but it would have to be some for of IF <my address> AND NOT received from mynetworks, REJECT. its spam and the FROM and TO are identical, i.e. from me and to me. Vernon
