You'll probably want to use fetchmail to collect the mail.  There are variants 
for MSN/Hotmail, AOL, and Yahoo, but you'll probably just use the built-in 
POP.  That will allow you to pass it to postfix for local delivery, and you do 
not need an official DNS served domain for that. 
 
You'll probably come up with some name to use internally.  If so, why not go 
ahead and register it?  Doesn't cost much, and if you ever do go "public", 
you're all set.  Otherwise, if your internal domain leaks out some dope is 
likely to register it "for" you, and then offer to sell or lease it back.  
Using web-based search services to locate a domain, but not purchasing it at 
the time, often results in finding that the service owner has scooped you on 
it.  Use host, dig, or nslookup, and be ready to buy when you do.
