I wouldn't say it's hard at all.  The tools are all available for
fedora to handle these tasks (often more than one, ala sendmail,
postfix, or exim for smtp).

If you want your fedora box to be the place all your other internal
systems get their mail through you could setup fetchmail or getmail to
retrieve the mail for all the accounts you wanted and have them
delivered to local mailboxes.  Then you can connect to the fedora box
via IMAP or POP3 to read the mail.  For sending mail you can configure
Postfix (or Sendmail or Exim) to accept mail from your LAN and relay
it through your ISP.  DNS and DHCP aren't too bad to setup either.

I'd check out howtoforge.com and see if there are any guides that will
get you started on these tasks.  Years and years ago I read a series
of articles in Linux Gazette that walked me through setting up much of
this stuff for a home system and I found it very helpful.  The details
there are perhaps a bit out of date, but the general idea is the same
still.  You can find those back issues via google.  Try searching on
"mail for the home network" and you'll see the first hit.

Only if you're already halfway in the grave. :)

I think I had it setup over a period of a few weeks.  I've learned a
lot and changed things since then, but I had the basic setup done
reasonably quickly -- considering that I was pretty new to all of this
stuff and to linux as well.
