Exim passwords stopped working

AAAARRRRGGGHH!!

After all of the problems yesterday with nobody being able to access webmail since the cPanel 11 update, now thousands of users on my system cannot get at their email at all because their pop3 passwords are being rejected. This is affecting every user on the system.

What can be done to fix it?

Thanks

OK. I just learned something new.

I don't think so, but how do I find out?

I also have no idea what "tail-f"ing is, but I have a little bit of my maillog here (names changed to prevent the innocent):

Does this help? How do I see if authdaemond is running &/or how do I start it if it isn't?

Thanks

Brian
