/**
|
| 5 |
* @file
|
| 6 |
* Enables Drupal to send e-mail directly to an SMTP server.
|
| 7 |
*
|
| 8 |
* This module uses the PHPMailer class, originally by Brent R. Matzelle, now
|
| 9 |
* maintained by Codeworx Tech.
|
| 10 |
*
|
| 11 |
* Overriding mail handling in Drupal requires setting the smtp_library
|
| 12 |
* variable with the filename of a file containing a drupal_mail_wrapper()
|
| 13 |
* function. This module sets the smtp_library value to point back to this
|
| 14 |
* file which contains the drupal_mail_wrapper() function that uses the
|
| 15 |
* PHPMailer class to send e-mail instead of the PHP mail() function.
