Sounds like you're with a hosting company that's slapping on security restrictions willy-nilly in a panic instead of properly securing the server.

You should NOT have to do this, but if your hosting company isn't willing to secure their server more efficiently you'll have to manually edit lines 447 and 456 of the class.phpmailer.php file and add an @ symbol in front of the ini_set() function call on both lines to cause PHP to ignore the error.
That doesn't really solve anything other than suppressing the display of the error message. The problem will still exist, and you may actually have trouble getting the emails to go through due to the break in functionality caused by the PHP restrictions imposed by your host.

I would expect that *all* emails from your store are equally affected, both admin and storefront.

Problem solved, thanks!

I've contacted my host.

We managed to solve this using PHP. (the client's hosting company was refusing to change server settings)
