I wasn't expecting to find my email there but I did expect to be able to use Thunderbird to download my emails.

This is what I am trying to achieve. I want a mail server, obviously, with the ability to use both POP3 and IMAP. I usually download my emails on my laptop (and the other users, like federica, on their PCs), but I want also to be able to install a webmail (most likely squirrelmail). Finally I want to install majordomo to manage some MLs. What do you suggest then?
