I saw yesterday the bad headers coming through and thought that it might have to do with his mail sending agent in some way. I send mail to Mr. Adelman with my reply to his query. Now I see that it has happened again. I have never seen this problem before. Perhaps it is related to the problems with LISTSERV headers previously reported? The REPLY-TO Field seems to be the one to worry about. /Geert *** Posting: *** Received: from BITNIC(MAILER) by QUEENS (Mailer X1.24) id 1819; Mon, 10 Aug 87 11:37:25 EST Received: by BITNIC (Mailer X1.24) id 2697; Mon, 10 Aug 87 11:36:53 EDT Date: Mon, 10 Aug 87 07:29:33 PDT Reply-To: Adelman Lbl.Bitnet Kenneth Adelman Sender: BITNIC MAIL-L List <MAIL-L@BITNIC> Comments: Warning -- original Sender: tag was From: Kenneth Adelman <[log in to unmask]> Subject: LISTSERV problems(?)

Anyone have any idea who is doing this corruption? The message also picked up a: Comments: Warning -- original Sender: tag was line, and I have no idea why or what it means.
