There are several ways to access mail on this server. You can ssh in and use mutt, you can use pop3s, you can use imaps, or you can use webmail. These all work reasonably well together (though, webmail works better with imap than with pop3). If you use imap and/or webmail, your folders will be in the 'mail/' directory in your home directory (if you are ever interested in using mutt to read them, of if you want to back them up).
