That depends entirely on the services you intend to offer.
IMAP requires TCP-143
News (NNTP) requires TCP-119.
Exchange connectivity requires RPC packet filters (lots of them).
Is the Exchange server still tied to a domain?

  I know that placing a Exchange 2K box in the DMZ is big headache, and that 
the gains not always worth the hard work.
  But what a about a Exchange 5.5 box?
  What's really involved? 
  Besides SMTP's and POP's which other ports would I have to leave open ?

  Many tks in advance,
