Mail.php problem

[ThomasHg]

I recently had a problem with the mail.php file which gives me the following error:

PHP Fatal error:  Uncaught Error: Class 'Swift_RecipientList' not found in /override/classes/Mail.php:107

After contacting support, I was told it's caused by Aretmic's Contact Form module

Here is the code of the Mail.php page :
