/**
 * @file
 * Enables Drupal to send e-mail directly to an SMTP server.
 *
 * This module uses the PHPMailer class, originally by Brent R. Matzelle, now
 * maintained by Codeworx Tech.
 *
 * Overriding mail handling in Drupal requires setting the smtp_library
 * variable with the filename of a file containing a drupal_mail_wrapper()
 * function. This module sets the smtp_library value to point back to this
 * file which contains the drupal_mail_wrapper() function that uses the
 * PHPMailer class to send e-mail instead of the PHP mail() function.
