[Mailman-Users] Mailman list size limitations?
Hi All, I have a client who wants to setup a very *large* mailing list. Right now she has about 4500 people on the list (including myself). However, she has reported that people aren't getting her emails (she sends only about one per month), and she's tried to send two so far. They show up in the archives, so I know that they are at least being received by mailman. Furthermore, I have been getting them - so it *seems* like it is working. But she absolutely insists that they are not going out, saying that she has asked other people who are subscribed to the list, and they have not received her message. Is there an error log I can take a look at it? And also, do you know offhand if I am asking for trouble with such a large list? Are there problems that crop up when I have such a large list? If mailman is not able to handle such a large mailing list, what do you recommend? I would prefer something open source that will run on a LAMP stack. Thanks for any feedback!

Your best (and only) option is to look at the send log of the MTA. Well, I lied, look at the member options and make sure that the other members aren't set for no mail. You could also add a few more test addresses... z! -- 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=showamp;file=faq01.027.htp

This is not particularly large for a Mailman list.

There are mailman logs, particularly 'smtp' and 'smtp-failure', but also 'error'. Also look at your MTA logs.

What is the largest known MM list out there? We're thinking of using it for a list that currently contains 400,000 entries, though probably about 20% of those should be discarded/are dead.

I've run lists on mailman over 40K. I run lists where the testing group is probably 4500... Is there an error log I can take a look at it? ~mailman/logs also, the logs generated by the mail delivery beast as well.

If mailman is not able to handle such a large mailing list, what do you recommend? mailman's not the problem. if it's a capacity issue, it's the computer that's likely too slow/small, but even there, I wouldn't except problems with 4,500 users on any platform remotely recent. -- 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=showamp;file=faq01.027.htp
Re: [Mailman-Users] Mailman list size limitations?
What is the largest known MM list out there? I can go to about 50K, on moderately slow hardware (sun E250). An xserve can handle that without breaking a sweat. We're thinking of using it for a list that currently contains 400,000 entries, though probably about 20% of those should be discarded/are dead. I'd say you're probably asking for problems, unless you use multiple lists and an umbrella. It might work, I'd be really curious how the internal pickles scale to that. I think you're likely to his disk I/O issues. When my stuff started getting large, I wrote systems customized for large-scale delivery and management. My guess would be without a good, random backing store database for the subscriber list, anything that large would really struggle. I'd definitely want that subscriber list in SQL somewhere. -- 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=showamp;file=faq01.027.htp

They show up in the archives, so I know that they are at least being received by mailman. Furthermore, I have been getting them - so it *seems* like it is working. Is there anything in common in the domains to which the failing messages are being addressed? (One domain or a few domains fail?) If so, she should find out whether those domains are willing to talk to her server (or are willing to talk to her server when it sends many recipients in the same message or many messages in the same connection). If personalization is on to any degree, then it's one recipient per message so that's not an issue. The outgoing MTA log should help a lot. --John -- 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=showamp;file=faq01.027.htp
