Because I wanted a quick resolution I called support, but they had no quick ideas. List has 16k subscribers, highly active. I noticed it had validate=no, so I strongly recommended validate=yes,confirm. Owner tries, and reverts to no quickly because gets lots of delivery errors (no, not from commands, real delivery errors to list members). We reconfigure the list so I get the errors, and try again: same result. Why should validate affect this? Note that it does not have an auto-delete parameter. Here's the header, edited for confidentiality: * Subject-Tag= listname * Review= Owner * Subscription= Open,Confirm * Send= Private,NoMIME * Reply-to= Sender,Respect * Files= No * Moderator= xxxxxx * Language= NoHTML * Attachments= No,Filter * Errors-To= [log in to unmask] * Confidential= No * Validate= No * Sizelim= 600 * Default-Options= Repro,Review * Digest= Yes,Same,Daily,03:00,Size(550) <bunch of filters deleted> * Daily-Threshold= 175 Here's a sample delivery error, also edited: From [log in to unmask] Thu Jul 7 15:37:58 2005 Return-Path: <> Received: from mailer.syr.edu (mailer.syr.edu [128.230.18.29]) by mailbox.syr.edu (8.12.10/8.12.10) with ESMTP id j67IJYv9028861 for <[log in to unmask]>; Thu, 7 Jul 2005 14:19:35 -0400 (EDT) Received: from listserv (listserv.syr.edu) by mailer.syr.edu (LSMTP for Windows NT v1.1b) with SMTP id <[log in to unmask]>; Thu, 7 Jul 2005 14:19:34 -0400 Date: Thu, 7 Jul 2005 14:19:34 -0400 From: "L-Soft list server at Syracuse University (1.8e)" <[log in to unmask]> Subject: listname: error report from UNXMAIL.SHSU.EDU To: Listserv Manager at Syracuse University <[log in to unmask]> Message-ID: <[log in to unmask]> X-LSV-ListID: None MIME-Version: 1.0 Content-Type: multipart/mixed; boundary="RARDWdYBTUVSJeHJWbRGFaURYGWQVW" X-UIDL: 14="!a,]!!I2C"!U=o!!
