My hosting provider (webhosting.uk.com) for security reason has disabled the PHP mail() function requiring to update our code using a SMTP authentication. I have no idea how to change the code, I suppose is in the sapphire folder? At the moment the contact form on my website doesn't send the email to the recipient and the newsletter module fails to send... Can anyone help me in this, or point me in the right direction?
Thanks in advance
You have to extend the Mailer class and make your own implementation.
When you've made your own implementation you put
$mailer = new My_Mailer();
in your _config.php and off you go. Have a look at the Mailer class for what you need to implement in your extension.
