Postfix is the server that moves mail from place to place. so you logged in as federica and sent an email to giulio. Did you then log in as giulio and try to read the mail? I haven't used mail in so long I am not sure if it works with maildir. I think it reads from /var/spool/mail or /var/mail directly, but you have set postfix to deliver to Maildir stores. You can also install squirrelmail on the server and apache, and then just log in to http://yourserver/webmail and read mail that way. But you would also have to make sure dovecot is set up. Have you thought of just using something like SME server (based on CentOS 4) as your server? It does most of the work for you, and has a very user friendly admin system through web pages. -- MailScanner is like deodorant... You hope everybody uses it, and you notice quickly if they don't!!!! -------------- next part -------------- A non-text attachment was scrubbed...
