There are various ways you can set up machines with mail in a LAN. If you want a centralized mail server then that machine must be powered up and running all the time. Is that what you want to do?
If so, you just install sendmail or postfix or exim on that machine and have all incoming mail put in a spool directory on that machine.
But how do the mail clients on the other machines read the mail?
Either you NFS mount the mail spool on each client, or yuck, yuck, yuck, use SAMB, or you run a pop server and then the clients have to run fetchmail to grab their mail.
But for a client machine, how are you going to get the mail to that machine? Standard mail clients are not going to work, because they are mail clients (MUAs) and not MTAs, so they do not speak SMTP. The only thing you could use would be something like Netscape mail.
As to squirrelmail, I have absolutely no idea since that is not a standard Unix mail utility. If you want to know how it can be used, then visit its web page.
