exim configuration

[Jesse Goerz <jgoerz@linuxfreemail.com>]

I'm trying to setup a server on my home network and I need some advice on how 
to setup exim.

Here's my network config:
One Debian server, one debian workstation, fiance's winbox.  I use a 56k 
modem to connect to the internet. (Currently only 3 users, root, me, and 
fiance)

I'm trying to keep all my mail on the server (I do a lot of testing with my 
workstation and reinstall quite often, and no, putting my mail on the winbox 
is not an option.)  

Here's my plan in plain english:
1.  Logon to the internet.
2.  *Automatically* grab email from 2 different ISPs and put on local Debian 
server.
3.  Access email on local Debian server from Debian workstation and winbox.
4.  *Leave* email on Debian server, do not transport to workstations.
5.  Send email using smtp.  
6.  Rewrite all local network addresses to reflect ISP email addresses.
7.  Log off of internet.

I am semi-familiar with fecthmail and exim from reading parts of the man 
pages and also following the posts on this list but I was hoping someone 
could help me out by suggesting a configuration/programs to use to make this 
happen.

TIA,
Jesse

P.S.  I am familiar with the use of sgml-tools and if I can sucessfully get 
this set up I plan on writing a quick/mini howto on how to do this.
