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"? > Do you have any other services running on this machine which are > accessible via TCP/IP from external hosts?

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