I'm getting a ton of these, but I'm unable to do anything about them because they have me competely baffled. I understand what the error is, but can anyone help me figure out how to find out the identity of the sinner so I can straighten him out. I haven't heard any complaints from any of my subscribers. This list is only about two months old. The complete error message follows: The enclosed mail file has been identified as a delivery error for list NONSUCH-L because it was sent to the reserved 'owner-nonsuch-l' mailbox. ------------------------------ Message in error ------------------------------- Received: from emin19.mail.aol.com (emin19.mail.aol.com [152.163.125.17]) by listserv.aol.com (8.6.12/8.6.12) with ESMTP id DAA26868 for <[log in to unmask]>; Fri, 29 Nov 1996 03:14:43 -0500 Received: by emin19.mail.aol.com (8.6.12/8.6.12) id DAA19402 for [log in to unmask]; Fri, 29 Nov 1996 03:26:26 -0500 Date: Fri, 29 Nov 1996 03:26:26 -0500 Message-Id: <[log in to unmask]> From: [log in to unmask] Subject: Returned Mail: Undeliverable To: [log in to unmask] The mail you sent could not be delivered to: 550 [log in to unmask] is not a known user The text you sent follows: From [log in to unmask] Thu Nov 28 21:18:28 1996 Return-Path: [log in to unmask] Received: from listmail.aol.com (listmail.aol.com [152.163.200.7]) by emin19.mail.aol.com (8.6.12/8.6.12) with ESMTP id VAA08263; Thu, 28 Nov 1996 21:18:28 -0500 Received: from LISTSERV.AOL.COM by listmail.aol.com (LSMTP for Windows NT v1.0a) with SMTP id 81D54020 ; Thu, 28 Nov 1996 21:17:06 -0500 Received: from LISTSERV.AOL.COM by LISTSERV.AOL.COM (LISTSERV-TCP/IP release 1.8c) with spool id 657199 for [log in to unmask]; Thu, 28 Nov 1996 21:06:44 -0500 Received: from emout13.mail.aol.com (emout13.mail.aol.com [152.163.125.39]) by listserv.aol.com (8.6.12/8.6.12) with ESMTP id VAA03306 for <[log in to unmask]>; Thu, 28 Nov 1996 21:06:40 -0500 Received: by emout13.mail.aol.com (8.6.12/8.6.12) id VAA18091 for [log in to unmask]; Thu, 28 Nov 1996 21:18:21 -0500 Message-ID: <[log in to unmask]> Date: Thu, 28 Nov 1996 21:18:21 -0500 Reply-To: Nonsuch Yacht Owners Discussion List <[log in to unmask]> Sender: Nonsuch Yacht Owners Discussion List <NONSUCH-
