There are 2 options in Universal Email:
Mail - this uses the php mail() function which sends through sendmail. the mal() funciton does not support SSL, or authentication
Pear Mail for SMTP - this option allows you to pass a user name and password and use SSL To connect to the mail server.
Pear Mail is the only option in Universal Email that will work for this host if they require authentication.
The page they sent a link to is a pearl script, not php.
