The Message-ID header is it. In your message that was Message-ID: <[EMAIL PROTECTED]> I'm not sure if clients are required to add (some clearly do) but if not, then the first SMTP server to handle a message is supposed to add it. To insure there's one there, I believe the implementation is essentially for each server to check for its presence and add it if not there. -- Larry Stone [EMAIL PROTECTED] http://www.stonejongleux.com/ -- To unsubscribe: <mailto:[EMAIL PROTECTED]> archives: <http://www.mail-archive.com/entourage-talk%40lists.letterrip.com/> old-archive: <http://www.mail-archive.com/entourage-talk%40lists.boingo.com/>
