If you just want email local to your LAN, one way (probably not the best) is
to setup your email daemons (pop3, smtp) under tcpwrappers and only accpect
connections from known ip's on the LAN. Also if you have a firewall, setup
to reject all incoming connections (from outside the lan) to ports 25 and
110 on the email server (reject all connections to the email server if
possiable from the outside.)
For example in hosts.allow (assuming your running your pop3 and smtp daemon
from inetd) you could have something like this
pop:192.168.17.
smtp:192.168.17.
Assuming everything in 192.168.17.* is you LAN
in hosts.deny have something like
ALL:ALL
If all email accounts are under one domain running off one machine you
should be able to just send email to "username" and they will get it.
There is other ways, not saying this is the best way
