I'd like to communicate with some friends via email. Currently, I just have a group in my Thunderbird address book and I just send emails to the whole list.
It is cumbersome for them to answer to everybody, so I'd like to set up a mailing list like Debian uses.
I do have a simple PHP/MySQL Webserver, but that is about it. A friend of mine has a complete Ubuntu Server that I could use.
What software could I use to get a mailing list with a web interface for subscription and an NNTP access so that I can read through the mails using KNode?
