Actually, to correct my previous mail, this appears to be a post ezmlm issue (ie, entirely a qmail issue). Why? Because of this: (From two different dups of my last message) >From dragaera-return-14277-mneme=io.com at dragaera.info Fri Jul 9 12:19:15 2004 X-VM-v5-Data: ([nil nil nil nil nil nil nil nil nil] ["1027" "Friday" "9" "July" "2004" "12:12:18" "-0500" "Joshua Kronengold" "mneme at io.com" nil nil "OT: dups" "^From:" nil nil "7" nil nil (number mark " Joshua Krone Jul 9 1027 " thread-indent "\"OT: dups\"\n") nil nil] nil) Return-Path: <dragaera-return-14277-mneme=io.com at dragaera.info> Received: from redbaron.io.com (redbaron.io.com [209.198.128.80]) by webmail.io.com (8.12.8/8.12.8) with ESMTP id i69HJFrA024951 for <mneme at io.com>; Fri, 9 Jul 2004 12:19:15 -0500 Received: from dd-b.net (IDENT:qmailr at gw.dd-b.net [63.224.10.74]) by redbaron.io.com (8.12.11/8.12.11) with SMTP id i69HJBgM057101 for <mneme at io.com>; Fri, 9 Jul 2004 12:19:12 -0500 (CDT) (envelope-from dragaera-return-14277-mneme=io.com at dragaera.info) Received: (qmail 23355 invoked from network); 9 Jul 2004 17:19:06 -0000 Received: from unknown (@10.0.0.205) by 10.0.0.205 with QMQP; 9 Jul 2004 17:19:06 -0000 >From dragaera-return-14277-mneme=io.com at dragaera.info Fri Jul 9 12:17:42 2004 X-VM-v5-Data: ([nil nil nil nil nil nil nil nil nil] ["1027" "Friday" "9" "July" "2004" "12:12:18" "-0500" "Joshua Kronengold" "mneme at io.com" nil nil "OT: dups" "^From:" nil nil "7" nil nil (number mark " Joshua Krone Jul 9 1027 " thread-indent "\"OT: dups\"\n") nil nil] nil) Return-Path: <dragaera-return-14277-mneme=io.com at dragaera.info> Received: from defender.io.com (defender.io.com [209.198.128.79]) by webmail.io.com (8.12.8/8.12.8) with ESMTP id i69HHgrA023895 for <mneme at io.com>; Fri, 9 Jul 2004 12:17:42 -0500 Received: from dd-b.net (IDENT:qmailr at gw.dd-b.net [63.224.10.74]) by defender.io.com (8.12.11/8.12.11) with SMTP id i69HHe1i034802 for <mneme at io.com>; Fri, 9 Jul 2004 12:17:41 -0500 (CDT) (envelope-from dragaera-return-14277-mneme=io.com at dragaera.info) Received: (qmail 22916 invoked from network); 9 Jul 2004 17:17:33 -0000 Received: from unknown (@10.0.0.205) by 10.0.0.205 with QMQP; 9 Jul 2004 17:17:33 -0000 Note a couple of different things: 1. The qmail message ID (in this case, 14277-mneme=io.com) is identical. 2. The recieved from unknown line has different times -- this seems to indicate multiple internal redilivery attempts with pseudo-failures. So what appears to be happening is that when ezmlm sends the mail to qmail (or some similar hop -- that last line), it gets a false negative and retries. Solution 1: figure out what is causing the false internal negatives and stop it from happening. Solution 2: deal with the occasional lost message, and don't retry errors found in this stage. -- Joshua Kronengold (mneme@(io.com, labcats.org)) |\ _,,,--,,_ ,) --^-- "Get your mind right and you can make a stick /,`.-'`' -, ;-;;' /\\ your wand and the sky your hat and a puddle |,4- ) )-,_ ) /\ /-\\\ your magic..." -- Granny Weatherwax '---''(_/--' (_/-'
