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.
This is a python extension module to enable python scripts to attach to
sendmail's libmilter functionality. Additional python modules provide for

recipients, STARTTLS...
Thunderbird Labels plugin for RoundCube webmail.
Displays the message rows using the same colors as Thunderbird does.
Label of a message can be changed/set exactly like in Thunderbird.
This automatically tacks a message onto the end of messages as they're being
sent from SquirrelMail. It functions just like the Hotmail/Yahoo/etc. mail
services, with all of their little 'get your own free hoojamajiggy' messages.
This plugin displays a pull-down select box with IMAP server choices on the
login page. The user will be logged in using the IMAP server that is chosen.
RMail is a lightweight mail library containing various
