sendmail on RH 8 (and 7.3) is a maze of twisty little symlinks because
of the introduction of a tool called "alternatives" -- the idea being
that if you prefer postfix (as I do :-)) you can tell "alternatives"
to swap all the symlinks associated with sendmail, man sendmail, and
newaliases for the corresponding postfix equivalents.  Chris, is it
possible you're in an indeterminate state with neither one hooked up?
Seen it happen.  Find the sendmail startup script in /etc/rc.d/init.d
and follow the chain of links back to the actual binary executable.

Are you running sendmail as a daemon (i.e. all the time)?  Do you see
it running when you do a ps -ef?  If not:

Is there an S80sendmail in your /etc/rc.d/rc3.d ??  It should be a link
back to the init.d copy of the sendmail startup script. What happens if
you run the command "/etc/rc.d/init.d/sendmail start" -- does it say
"OK" or "FAILED"?

Good idea; duh, I just read a little further.  The fact that it's
apparently accepting connections from localhost strongly points to a
firewalling issue.

Not really.  Google is a lot more helpful.  RH8 is too new.
