Paraphrasing the website:
Mailman is a mailing list manager (MLM); that is, software to help manage
email discussion lists, much like Majordomo, LISTSERV, and the like.
Unlike most similar products, Mailman gives each mailing list a web page
and allows users to subscribe, unsubscribe, and change their preferences
via the web. Even a list manager can administer his or her list(s)
entirely via the web. Mailman integrates many common MLM features,
including web-based archiving (though it also has hooks for external
archivers), mail-to-news gateways, bounce handling, spam prevention,
Majordomo-style email-based list administration, direct SMTP delivery (with
fast bulk mailing), digest delivery, virtual domain support, and more.
Mailman is written mostly in Python (with a smattering of C where necessary
for security purposes), and includes hooks to make it easily scriptable and
extensible. It is compatible with most web servers and browsers, and most
mail transfer agents (mail servers). Mailman's documentation may be found on
its website.
Mulberry is back under new ownership and is now available for FREE!
Mulberry is a high-performance, scalable, and graphically groovy internet
mail client. It uses the IMAP (IMAP4rev1, IMAP4, and IMAP2bis) protocol for
accessing mail messages on a server, the standard SMTP protocol for sending
messages, and does lots and lots of things with MIME parts for mixed text
and "attachments" of many different types of files and data. Support for
POP3 and Local accounts, full disconnected IMAP support, PGP/GPG,
SSL/STARTTLS, local and SIEVE support for filtering and much more!
Please note that there is no official support for Mulberry now -
community support via mailing lists and other such resources will be
used instead.
