[Itai Tavor, on Wed, 24 Nov 1999] :: Hi, :: :: I need to add a newsletter feature to a Zope site.

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.
