<DIV><SPAN style="LINE-HEIGHT: normal; FONT-VARIANT: normal; FONT-STYLE: normal; COLOR: #000000; FONT-SIZE: 10pt; FONT-WEIGHT: normal">Thanks for the responses. I got to thinking some more about this, and I think I have it resolved in a way that's much simpler. I was whitelisting the server IP, but if I simply look for the server IP AND the sender address being their domain I should be able to tell email originated from them vs forwarded. It won't help with forwarded email that has a spoofed sender address being theirs but that's a tiny percentage and worth the risk IMO. </SPAN></DIV>
