After several months of a nicely functioning Mailman server, I opted to enable VERP yesterday. We're running MM 2.1.4 on SuSE with exim. Since then most everything has worked fine, until an announcement only list of 4000 sent a message earlier this afternoon. Of the roughly 4000 messages, about 1600 are now frozen in the exim queue.
The exim queue has lots of entries like this: 2005-02-03 12:27:31 1CwklP-0002Rm-5i <= [EMAIL PROTECTED] H=localhost (server.org) [127.0.0.1] P=esmtp S=47504 [EMAIL PROTECTED] 2005-02-03 12:27:31 1CwklP-0002Rm-5i ** [EMAIL PROTECTED] R=dnslookup T=remote_smtp: SMTP error from remote mailer after RCPT TO:<[EMAIL PROTECTED]>: host mxb.earthlink.net [207.217.125.26]: 550 [EMAIL PROTECTED] unknown . . . 2005-02-03 12:27:32 1CwklP-0002S1-Rp ** [EMAIL PROTECTED] <[EMAIL PROTECTED]> R=mailman_router T=mailman_transport: Child process of mailman_transport transport returned 6 from command: /usr/lib/mailman/mail/mailman Resulting in the following from syslog: Feb 3 12:27:32 list Mailman mail-wrapper: Illegal command: bounces+namepart=domain.tld It seems that suddenly large numbers of addresses are suddenly bouncing. Mailman is then chocking on the bounces. I followed the instructions from http://www.exim.org/howto/mailman21.html#verpin when I setup VERP. I'm not carefully reviewing those changes to check for mistakes. If anyone has insight into why so many addresses are suddenly bouncing, and why mailman is chocking on the bounces I would very much appreciate it. The other detail worth mentioning is that several smaller lists are continuing to function properly. This list was transferred some time ago from another server. There were some minor changes I had to take just after the migration to deal with odd settings that came in when the lists were moved. Everything seemed to be fine, but now I wondering if I missed something during the move. ------------------------------------------------------ Mailman-Users mailing list [email protected] http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://www.python.org/cgi-bin/faqw-mm.py Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/
