[Exim] Exim4 Mail Forwarding ?

Using exim4.30 on a small lan to which 3 computers are attached.
Also using fetchmail, procmail and spamassassin.

Mail program works perfectly using a basic configuration.

Wondering if it is possible to setup one machine (mailman:
192.168.1.250) to retrieve all mail and distribute copies to desktop
server (mom: 192.168.1.1) and notebook (libranet: 192.168.1.252).

If this is possible, what would I need to do (google search has turned
up very little).
