Set default to no rejection message
Before I got set the rejection so no rejection message would go out, permanently. If people get that notice then they complain but we usually have good reason do reject some messages.
But now you have check the box before each rejection notice. Just a bit of a pain when there is a bunch of them.
So if you reject a message via email and not the Web page, you get no chance to check the box saying dont send a rejection notice to the sender.
