Enables drupal to send email directly to an SMTP server using authentication. Uses the PHPMailer class by Brent R. Matzelle.

Class

SMTP

SMTP is rfc 821 compliant and implements all the rfc 821 SMTP commands except TURN which will always return a not implemented error. SMTP also provides some utility methods for sending mail to an SMTP server. @package PHPMailer @author Chris Ryan
