After the TECMTYVM Listserv was taken out of the backbone, our Listserv had to take over much of the distribution duties in Mexico, together with the ITESMVF1 server. With them came the "joys" of dealing with mismanaged nodes and broken down mail daemons. Another Mexican node, UDLAPVMS, has been giving us MAJOR headaches, since it is bouncing back all mail bound for it unexistent users, but it sends it back to our MAILER, instead of the list originator. Worse yet, it sends it via the Rice SMTP, then via NJE lines, exacerbating the link congestion problem at the MTECV1 junction. We are getting an average of 300 bounced messages per day, which the LMAILer dutifuly hands over to MAINT, MAILMNT OPERATOR and myself (i.e., 1200 extra files, as if our spool had nothing better to do). Attached below is a sample header. What can I do ? I have already tried asking/pleading/demanding/screaming- bloody-murder, to no avail. Can I disable the node entirely, until they get their act together ? Thanks for your insights. Juan Courcoul P.S. On an unrelated note, I finally managed to get a copy of VERS9401 NODUPD. Please disregard my previous request for an FTP site. --------- Typical bounced header: Return-Path: <@VMTECQRO.QRO.ITESM.MX,@RICEVM1.RICE.EDU:[log in to unmask]> Received: from RICEVM1.RICE.EDU (NJE origin MAILER@RICEVM1) by VMTECQRO.QRO.ITESM.MX (LMail V1.1d/1.7f) with BSMTP id 4347 for <[log in to unmask]>; Tue, 11 Jan 1994 20:40:42 -0600 Received: from RICEVM1 (NJE origin SMTP@RICEVM1) by RICEVM1.RICE.EDU (LMail V1.1d/1.7f) with BSMTP id 2442; Tue, 11 Jan 1994 19:23:35 -0600 Received: from udlapvms.pue.udlap.mx by RICEVM1.RICE.EDU (IBM VM SMTP V2R2) with TCP; Tue, 11 Jan 94 19:23:32 CST Received: by udlapvms.pue.udlap.mx (4.1/SMI-4.0) id AB06511; Tue, 11 Jan 94 19:20:11 CST Date: Tue, 11 Jan 94 19:20:11 CST From: [log in to unmask] (Mail Delivery Subsystem) Subject: Returned mail: User unknown Message-Id: <[log in to unmask]> To: [log in to unmask] ----- Transcript of session follows ----- 550 rmendez...
