 * Thanx for the plugin!
 * I just wanted to note that on some php installations the php_mycrypt.dll is not
   enabled which cause;
    `Fatal error: Call to undefined function mcrypt_encrypt()
   in E:\www\wordpress\wp-content\plugins\smtp\smtp.php on line 191`
 * So better to check first if the function exist.
 * Thanx
