1. Create a simple database program that stores the messages in a MySQL table. Columns for the tables would be to, from, messagedate and messagetext

2. Create notification script that sends e-mail after message is stored in database.

PHP has a built-in mail() function that allows you to send mail -- see http://www.php.net/mail.





That said, it sounds like you also need some sort of user authentication. This is a far more advanced topic; take a read at http://ca.php.net/session for information about PHP sessions.
