(Thinking aloud...and not seen all of earlier threads) - I don't think we can validate the originating server - only that it /has/ a reverse DNS entry. - But we can check that mail can be accepted at the originating address by opening an SMTP session and terminating it at "DATA". Not sure how practical this is...would be slow...the problem is the SMTP protocol which is very permissive (!). Using that protocol, I think we can only try to validate the data presented over it... -- Regards, PhilK Email: [EMAIL PROTECTED] / Voicemail & Facsimile: 07092 070518 “The basic tool for the manipulation of reality is the manipulation of words.
