Hi all- Pretty new to mailman, and have an "announcement only" list set up for a client. It's been working great for months - they send to 300 - 400 members a day. A couple of days ago, they uploaded 50,000 email addresses and sent out a post. It brought our T1 to a crawl. I'd like to avoid this in the future. Here's the specs:
mailman + postfix on a compaq dl380 with 2 800 Mhz P3 and 1.5 gig RAM Redhat 4 ES (or AS - can't remember at this point). resolv.conf points to the provider's DNS. We're on a T1 that is shared between two networks - our production and our office network (192.168.170. vs. 192.168.160.) This machine is in our office network and a couple of folks was pissed when the 50K mailing went out ;) The list server and postfix are pretty much out of the box - following the Mailman setup for postfix. The postfix MTA also does mail for a different client (domain), but I'm not doing Mailman/postfix/virtual domains. The other client just has 5 local mailboxes - not much volume at all. I've been reading up on performance tweaking in the mailman FAQ and was wondering where I should concentrate my efforts to avoid the listserver saturating my line. I'm thinking a local dns cache on the box would be good, but have seen anything that directly addresses how to "slow" the system down to avoid cramming the network. ------------------------------------------------------ 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/ 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
