My experience, which is mostly on windows boxes, is that while you can spoof the FROM you can not spoof the SENDER; which is automatically be tacked on if you don't code it in, or if you do code it in, will cause the mail call to fail if you attempt to spoof it. That said, I'm sure someone else on the list knows a way around this.

Alternately is there a way to take all these bad emails and feed it into a script to remove the bad email addresses from the MYSQL table?
