Nathan gave you the answer already, but a further breakdown of what's going on follows. At the end I'll make a suggestion or two. >SAMPLE ERROR MESSAGE FOLLOWS: First, some LISTSERV generated stuff: >Date: Tue, 2 Jun 1998 12:41:38 -0400 >From: "L-Soft list server at Brown University (1.8b)" ><[log in to unmask]> >Subject: BLUES-L: error report from BROWNVM.BROWN.EDU >To: David Silberberg <[log in to unmask]> >X-LSV-ListID: None > >The enclosed message, found in the BLUES-L mailbox and shown under the >spool ID >9378 in the system log, has been identified as a possible delivery error >notice >for the following reason: "Sender:", "From:" or "Reply-To:" field >pointing to >the list has been found in mail body. > >------------------------ Message in error (58 lines) >-------------------------- Then, the headers of the bounce: >Return-Path: <[log in to unmask]> >Received: from BROWNVM (NJE origin SMTP@BROWNVM) by BROWNVM.BROWN.EDU >(LMail V1.2a/1.8a) with BSMTP id 3733; Tue, 2 Jun 1998 12:41:38 -0400 >Received: from nut.brown.edu (128.148.19.196) by BROWNVM.brown.edu > (IBM VM SMTP V2R4) with TCP; Tue, 02 Jun 98 12:41:37 EDT >Received: from ux.accesscom.net (ux.accesscom.net [204.181.176.2]) > by nut.brown.edu (8.8.5/8.8.5) with SMTP id MAA29273 > for <[log in to unmask]>; Tue, 2 Jun 1998 12:41:45 -0400 (EDT) >From: [log in to unmask] >Message-Id: <[log in to unmask]> >Report-Version: 2 >>To: [log in to unmask] >To: [log in to unmask] >Date: Tue Jun 2 16:41:38 GMT 1998 >Original-Date: Tue, 2 Jun 1998 11:30:25 -0500 >Original-Subject: Re: Canadian Blues Bands? >Not-Delivered-To: !recipients due to 02 Invalid/Ambiguous >Originator/Recipient Name > ORIGINAL MESSAGE ATTACHED > (rmail: Error # 8 'Invalid recipient') >En-Route-To: exarch >Content-Type: text Then a blank line: > Then the message that bounced, with full headers: >Received: from listserv.brown.edu(128.148.128.155) by ux(smtpd 2.1.2) with >SMTP id smtp027166; Tue, 2 Jun 98 11:41:22 -0500 >Received: from stanley.cis.Brown.EDU (stanley.cis.brown.edu >[128.148.128.155]) by listserv.brown.edu (8.6.10/8.6.10) with SMTP id >MAA19599; Tue, 2 Jun 1998 12:32:30 -0400 >Received: from BROWNVM.BROWN.EDU by BROWNVM.BROWN.EDU (LISTSERV release 1.8b) > with NJE id 9213 for [log in to unmask]; Tue, 2 Jun 1998 > 12:31:03 -0400 >Received: from BROWNVM (NJE origin SMTP@BROWNVM) by BROWNVM.BROWN.EDU (LMail > V1.2a/1.8a) with BSMTP id 3400; Tue, 2 Jun 1998 12:31:03 -0400 >Received: from nut.brown.edu (128.148.19.196) by BROWNVM.brown.edu (IBM VM >SMTP > V2R4) with TCP; Tue, 02 Jun 98 12:31:02 EDT >Received: from mycroft.mexia.com (glade.net [205.148.251.4]) by nut.brown.edu > (8.8.5/8.8.5) with ESMTP id MAA25273 for ><[log in to unmask]>; > Tue, 2 Jun 1998 12:31:12 -0400 (EDT) >Received: from s193.mexia.com (s193.mexia.com [205.148.251.193]) by > mycroft.mexia.com (8.8.7/8.8.7) with SMTP id LAA09930 for > <[log in to unmask]>; Tue, 2 Jun 1998 11:32:10 -0500 >Received: by s193.mexia.com with Microsoft Mail id > <[log in to unmask]>; Tue, 2 Jun 1998 11:31:06 -0500 >Encoding: 8 TEXT >Approved-By: Bill Salmon <[log in to unmask]> >Message-ID: <[log in to unmask]> >Date: Tue, 2 Jun 1998 11:30:25 -0500 >Reply-To: Bill Salmon <[log in to unmask]> >Content-Length: 193 >Content-Type: text/plain >Sender: Blues Music List <[log in to unmask]> >From: Bill Salmon <[log in to unmask]> >Subject: Re: Canadian Blues Bands? >Comments: To: Patrick Hertel <[log in to unmask]> >To: Multiple recipients of list BLUES-L <[log in to unmask]> > >Pat Hertel asked: ><<"THE band?"

Also, it looks like the bounce came from ux.accesscom.net, so I'd look for subscribers from the accesscom.net domain. Hope this helps, jwgh
