I have started to receive mail errors for someone who has not been on my list for more than 6 months. The error indicates that there is no such user at that site and when I delete the name the listserv tells me that there is no such person on the list. I am also getting mail errors from an address which does not appear on my list and as far as I can tell never did but they are sending back copies of the posts to the list. I didn't forward copies in order not waste bandwidth if this is only a pseudo-problem that will disappear. Does anyone have any idea how these errors are generated? I remember someone at ASU mentioning the same type of error. Thanks. -- Paul. -- Dr. Paul S. di Virgilio, University of Toronto [log in to unmask]
