Email Help

[CPMatt]

Looking for some advice on how to point a script from my website to correct email servers on my Voda Host Webmail.

define( 'MAIL_FORMAT', 'html' );
//mail|sendmail|smtp
define( 'MAIL_TYPE', 'sendmail' );
define( 'SMTP_HOST', 'localhost' );
define( 'SMTP_PORT', '25' );
define( 'SMTP_AUTH', '0' );
define( 'SMTP_USER', '' );
define( 'SMTP_PASS', '' );
define( 'SM_PATH', '/usr/sbin/sendmail' );

Any ideas how this should look in my script?
