SMTP Godaddy - Intermittent sending & error - think its a patch problem?

Hi guys, i've set it up with the relay address and no login, but I keep getting the following error;

I'm getting the odd email that it's successful, everything is very intermittent and it's driving me crackers.

I think the problem might lie with the patch for phpmailer, there's three patches and I can't find half the text... can anyone copy and paste what the class.phpmailer.php should say or their working files or something?

Thanks in advance to anyone willing to help
