I somehow had this problem and posted about it several months ago. Back then, a complete reinstallation of mailman fixed the problem. This time, the reinstallation hasn't fixed anything. What follows will be a bunch of info from log files trying to follow a specific message.
I don't know if this is an exim problem (I have also removed exim and reinstalled it) or a mailman problem. Elsewhere people seem to have the same problem with other MTAs (that I've found in web searches), and the response is always "look in the MTA logs"--well, I've included the full bulk of the MTA logs pertaining to the message I follow. So please let me know if there's anywhere else I can dig around for information to try and get down to the center of the problem Thanks, --m On a different machine, I do this: zuikis.uchicago.edu -20:22:57- ~ > echo "hi" | mail [EMAIL PROTECTED] The following are commands run on the mailman server (and there was nothing appropriate in mailman/logs/error) lithchat.com:/mailman/logs# ../bin/version Using Mailman version 2.0.6 lithchat.com:/mailman/logs# uname -a Linux nida 2.2.19 #1 SMP An Rgp 14 21:36:28 CDT 2001 i586 unknown lithchat.com:/mailman/logs# exim -bV Exim version 3.32 #1 built 15-Aug-2001 00:13:26 Copyright (c) University of Cambridge 2001 lithchat.com:/mailman/logs# tail -2 /var/log/exim/mainlog 2001-10-22 20:22:32 15vqH2-0002FP-00 <= [EMAIL PROTECTED] H=zuikis.uchicago.edu [128.135.57.157] P=esmtp S=490 [EMAIL PROTECTED] 2001-10-22 20:22:33 15vqH2-0002FP-00 => test <[EMAIL PROTECTED]> D=list_director T=list_transport 2001-10-22 20:22:33 15vqH2-0002FP-00 Completed lithchat.com:/mailman/logs# tail -1 post Oct 22 20:25:02 2001 (8668) post to test from [EMAIL PROTECTED], size=138, 1 failures lithchat.com:/mailman/logs# tail -1 smtp-failure Oct 22 20:25:02 2001 (8668) -1 [EMAIL PROTECTED] (ignore) lithchat.com:/mailman/logs# tail -2 smtp Oct 22 20:25:02 2001 (8668) All recipients refused: host not found Oct 22 20:25:02 2001 (8668) smtp for 1 recips, completed in 0.089 seconds lithchat.com:/mailman/logs# tail subscribe Oct 22 02:32:57 2001 (2363) test: new [EMAIL PROTECTED] lithchat.com:/mailman/logs# python -S ../cron/qrunner lithchat.com:/mailman/logs# tail -1 smtp-failure Oct 22 20:36:01 2001 (8744) -1 [EMAIL PROTECTED] (ignore) lithchat.com:/mailman/logs# tail -2 smtp Oct 22 20:36:01 2001 (8744) All recipients refused: host not found Oct 22 20:36:01 2001 (8744) smtp for 1 recips, completed in 0.086 seconds lithchat.com:/mailman/logs# tail -7 /var/log/exim/mainlog 2001-10-22 20:22:32 15vqH2-0002FP-00 <= [EMAIL PROTECTED] H=zuikis.uchicago.edu [128.135.57.157] P=esmtp S=490 [EMAIL PROTECTED] 2001-10-22 20:22:33 15vqH2-0002FP-00 => test <[EMAIL PROTECTED]> D=list_director T=list_transport 2001-10-22 20:22:33 15vqH2-0002FP-00 Completed 2001-10-22 20:23:01 Start queue run: pid=8653 2001-10-22 20:23:01 End queue run: pid=8653 2001-10-22 20:38:01 Start queue run: pid=8757 2001-10-22 20:38:01 End queue run: pid=8757 ------------------------------------------------------ Mailman-Users maillist - [EMAIL PROTECTED] http://mail.python.org/mailman/listinfo/mailman-users
