The firewall I use is APF and other than adding some ROKSO spammer IP addresses and the Spamhaus DROP list to it about once a week, there hadn't been any changes to it. I'm not using ident in Exim either. Nothing else on the server had changed or been updated except for my normal maintenance of spam filters for Exim. Mailman hadn't had any changes at all for months, I installed the security patch from February 10th a few days later and that's it. I use cPanel/WHM for managing my hosting customers but that hadn't had any updates in a week, ten days before the mail delivery slowdown started. As for DNS, Bind seems to be running fine - nameserver issues was the first thing I thought of and after doing some checking, my server was using external name servers hosted by my server host. I changed that to use my local nameserver but there was no change to the mail delivery performance for that list. I did uncover one bit of info today, this list is on a domain that only hosts one other list (and practically nothing else, one tiny website with very little activity and both lists do not keep Mailman archives) and that other list is also having the same slow mail delivery. It hadn't had any posts in about a month and a message was posted today, processed by Mailman and sent to Exim at 16:38 pm EST today and it took 50 minutes for the message to go out from Exim to the 226 members on individual mail delivery. That pretty much the same delivery stats as on the other larger list. So now I suspect it's related to that domain. I'm going to do some digging in its hosting account settings, see if something got set oddly for it. It's one of my domains and for my own, I usually give them all options and features with very few restrictions but I may have mucked up something without realizing it.

I thought about the spool directory - Exim was set to "split_spool_directory = yes", had been ever since the server was set up in fall of 2003. I changed it to "no", that made things worse (far too many files in one folder, so I changed it back to "yes". I'll try your suggestion this weekend when traffic is lower, thanks much! -- hth, Stephanie Links blog: http://alice.ttlg.net/links/ Glenfinnan Web Hosting: http://www.glenfinnan.net/ The machine does not isolate man from the great problems of nature but plunges him more deeply into them. -- Antoine De Saint-Exupery [Wind, Sand, Stars] ------------------------------------------------------ Mailman-Users mailing list Mailman-Users@python.org 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/ Unsubscribe: http://mail.python.org/mailman/options/mailman-users/archive%40jab.org Security Policy: http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq01.027.htp
