> X-Mailer: Novell GroupWise 4.1 MMmmmh! Another fun feature of this software ... My guess ? This users has profiled BLUES-L like a local user so some kind of "Novell" acknowledge becomes a "bounce" for LISTSERV since its addressed to "owner-LIST@HOST" ... My suggestion: Set the user [log in to unmask] NOMAIL, send a full copy of the bounce (including all headers) and tell him to go his local Tech support and notify you when he solved his problems. For more knowledgeable Lers can this "open acknowledge" be related with GroupWise handling of attachments ? Or some security "feature" maybe ? BTW Don't you love it when error messages are MIMEd and even with attachments ;-) Good luck ... -- Eric Paul-Hus, BLUES-L PS Novell GroupWise ? I'll reckon they have an e-mail Group but judging by their mailer behavior I'd called them GroupUnWise ? :->
