[ILUG] Linux as a mail server

[Rory Mac Mahon]

Hi
I would like to know how to configure my Redhat 6 system to act as a
mail server for my schools computer room.  We already have a WinNT server
which has become very slow and is constantly crashing this used to be our
mail server until I decided to relieve it of it's duties.  I
would also like to know how I would setup a webcaching server with Linux to
serve 30 machines running Win95 over a 100 Mb network.
