This is a very bad idea, to illustrate why here is the envelope sender of your message (that I'm replying to): Return-Path: <owner-postfix-us...@postfix.org> ...and here is the From: header: From: Adam Moffett <adamli...@plexicomm.net> Obviously the two don't match, and equally obvious is that your message is not SPAM.
