So when I go to reassign activities to my coworkers, for example follow up on an email campaign, I keep getting this failure notice? Any idea why?
"Hi. This is the qmail-send program at

I'm afraid I wasn't able to deliver your message to the following

This is a permanent error; I've given up. Sorry it didn't work out."
