[Nottingham] Local server

[David Aldred]

I'm looking at setting up a machine as a server for my local LAN.  Ideally, it 
will provide POP mail services to all users on the LAN, DNS, a newsserver, 
and a web cache.

The DNS, newsserver and web cache functionality looks fairly easy to set up: 
POP mail (collecting mail from my ISP, with spam and virus filtering, and 
sending any mail generated from the A via the ISP) looks more complex - I've 
found several HOWTOs of varying ages, most of which are very involved.

Does anyone know any easy way of doing this, or do I just need to print off a 
big HOWTO and work through it?  

(I suppose in a way I'm quite surprised there isn't an 'ISP in a box' system, 
given Linux's acknowledged usefulness in this sort of area).
