Your first step should be to capture the conversation. For myself, I'd use a recent version of BLAT, and turn up the logging to very verbose, and see if you can find out what's going wrong. If that doesn't reveal anything, I'd turn up the SMTP logging on the Exchange server, and see what that reveals. Also, it's a little unclear the path the email in some of your tests is taking. Does all mail pass through the Exchange server, or do some Outlook clients connect to a SCO box which then delivers it to the world? Might ask the SCO admins what they mucked with, too. Don't go mucking about in senmail.cf unless you absolutely have to - that's my philosophy. Actually, my philosophy is to replace sendmail with postfix whenever I can, but I'm guessing that's not an option here... Kurt
