Help on POP3 proxy setup

[scuba at centroin.com.br]

Hi Igor,

	It's working now, thank you.
	Just two points:
	
	kill -HUP does not work if I want to reload the modified 
mailauth.pm module. Not a real problem, though. 

	Since it's not doing any real authentication task (it's passed 
direct to the pop server) an wrong login/pass returns an "Internal Server 
error", the connection is droped and holds the mailbox locked until the 
popper server timeout.

|This is working prototype (I've tested it now), just set IP in Auth-Server
