I think I've looked at everything available and am convinced that Dan Bernstein's qmail/ezmlm offer the best performance, security and ease of maintenance. Have a look at www.qmail.org and www.ezmlm.org (qmail is the MTA and ezmlm the mailing list manager -- they work hand in hand).

You can run a dedicated list server with the qmail/ezmlm combo on a castoff 486 machine under Linux and it will be plenty fast enough for your needs. I think both apache.org and redhat.com still handle all their mail on low-end Pentiums with qmail.

I administer 20 mailing lists this way and never have to touch them.

What I need is quite different from what a mailing list program like ezmlm or Mailman does - The newsletter is one-way only - no user submissions, no question/reply threads. - I need full control over the format of the newsletter - can't just email entries to the list manager. - Users can only register and de-register, so I don't need user-accessible configuration screens. - This site will eventually get a user registration system for customizing the interface (Portal Toolkit?), and I'd like to use the same registration interface for the newsletter. So if I wanted to use a mailing list program, I think I'd have to do a lot of work to force it into my desired frame: My Zope registration code will have to register users with the mailing list. Then I'd have to email each news item to the mailing list so it gets included in the next digest. And I'd have to hack the program code to control the digest format. Looks like a whole lot of work trying to force an inappropriate tool to do what I want. The only part of a mailing list system I really need is the bulk mailer. I need to do the user registration inside Zope anyway. And the content gets generated by Zope so I don't need the mailing program to format it. I just need something that can deliver a message to 10,000 recipients quickly and efficiently, and has support for suspension of recipients that bounce too often. Is anybody familiar with Mailman or ezmlm enough to tell me how hard it would be to bypass all the mailing list handling functions and get straight to the bulk mailer? Or, is there a standalone bulk mailer program I can use? One other thing: This site is hosted on a dedicated server in a web farm (yes, I'm 100% buzzword compliant), and I would need a very good reason to justify getting a second server. Since my newsletter won't receive email and will only mail out once a week, can I expect to get by with running it on the main server? Or will mailing out 10,000 messages at once kill the Zope server performance for an hour every time?
