I'm sorry, I'm a little touchy about it. I've spent the last 3 days doing almost nothing but trying to fix our email issues. I haven't even really been able to do any work on MTurk because I've been stressing over it so much. But like I said, I've done what I can for now. I've been keeping an eye on our mail log and I'm already seeing fewer "deferred due to user complaints" messages than I was yesterday, but there's still a lot. I'm hoping it will work itself out now, but I think it's going to take a few days.
