A mailing list manager with an excellent web interface
GroupServer is a mailing list manager: an email sent to one address is then sent on to many people. In this way it is a list server like GNU Mailman. GroupServer also has an integrated web interface, so you can use the web to post, read the archives, and administer your groups. It is a bit like Google Groups. GroupServer gives you an open source system under your control: your groups, on your site, on your hardware.
