There is *no* incoming mail or outgoing mail, I read my mail elsewhere
by connecting to a remote system using ssh.  All I want is to be able
to see mail sent to root on the local system so I can monitor it.

easier to configure.  But now I don't want any sort of mail server
except to get the local delivery of root mail.

Where from?  It's not going to work from most places because the
firewall doesn't allow connections on port 25, this system isn't
intended to accept any mail from outside.
