       $mail->AddAddress($admin_email , "John Doe");
           $mail->Send();
       }

The error message is a bit misleading, but the problem is clear. The From: header must contain a domain as a complete email address. If your $smtp->from contains www.mysite.com, that is an invalid email address, missing the part after @. The mailer misinterprets your domain name as only the first part of an email address (the user part) and complains that it needs @domain to go with it. Supply a full sender email address to your $smtp->from property.

 // Should be something like [e-mail]
 $mail->From       =  $smtp->from ;
