Hello again, ... and thanks for the many responses, especially from Eric who had mail in my RDR within 5 minutes! I fully understand why the mail was rejected - because of the From: line in the mail, and I have no problem with that except that I didn't see why a properly quoted (with the > in front) line should be taken as a reject. However, I am sure that I have never seen a rejected mail item that has had the error prefixed with the > sign. Having said that, I think that within 2 minutes, some Un*x site will prove that they can send back mail like that on a regular basis :-). And so ... I will just have to instruct the members of all my lists to make sure they send mail that has not had this from line nonsense done to it. Thanks to all for your assistance. /Geert
