I use v2.03 and its a bit buggy, so will look at vrs 3, but it is a very good script.....

here is what you need to set in the imap globals:

<?php
// pop3 mail server connection parameters
$MailHost = "{sitename}";
$MailUser = "youremail@youremail.com";
$MailPassword = "youremailaccountpassword";

?>

Just add your e-mail address to the mailuser field, and the e-mail account password.

That's it.
