If I understand this correctly, and there's no guarantee of that, this 
shouldn't be a problem, because I POP my server all the time from 
Mozilla.  Right?
No clue on the authentication thing though.
I'm going to follow the link Jesse sent, and if that doesn't work I'll 
either wait for install fest (and hope I have a way to get there) or 
invite someone over to fix it in exchange for free cooked food.  We'll 
see how desperate I get.
