BTW, I just realized you said "authorized MX", which implies you are checking the connection address against the returned MX. I'm not doing that. I'm simply checking to see if the RHS of MAIL FROM *has* an MX. So, for example, if I received mail from [EMAIL PROTECTED], I would do an MX lookup on yahoo.com. If I found an MX (*any* MX), that test passes. It would only fail if the RHS lookup found no MX. I do validate the connection IP address in other ways, however. - To unsubscribe from this list: send the line "unsubscribe xmail" in the body of a message to [EMAIL PROTECTED] For general help: send the line "help" in the body of a message to [EMAIL PROTECTED]
