While helping one of our users sending a piece of mail to an - in terms of networks - far away user I got a rejection which first seemed weird. It consisted of four or five headers added by UAs containing path- and routing information and other nonsense comments. The last one was from a daemon which said *unbalanced "* - but there was no indication how the "To:"-field looked when it received it. Of course the "To:" and "From:" changed their contents at every UA on the way ... The address was long but otherwise simple and contained a true name in the form "Joe J. Jones" we tried it with "Joe J Jones" - see, it worked. And the form of the rejection Mail - I don't think LISTSERV would have been able to make any sense out of it ... it was almost uninterpretable for the human postmaster :-) .... Christian
