it is up to you, in which format you store the mail. and the fact that you use mozilla says that you don't store it in a Maildir format.
how you get your mail from your friend and how to handle your mail on your server are two different stories.
right i think the best is perhaps to install squirrelmail and read my mails with it , no ? because i know a little about mutt and i search a graphic client
thanks
