"Hi. This is the qmail-send program at machsupport.com.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out."
I got this when typing in the email address wrong, so its a valid message from the server. Wherever you sent the email to must have a full inbox, but, I told Scott about about this anyways.
