Just to make sure that the smart host made it into sendmail.cf do "grep 
'^DS' /etc/mail/sendmail.cf" -- You should see "DSmailhost" and not "DS".

I don't recall exactly what happens with the smart-host, but sendmail 
does have a preference for fully-qualify names (eg mailhost.example.com) 
and also prefers names to be in the DNS rather than in /etc/hosts.    
You could try making sure that the FQDN for mailhost appears on the line 
in /etc/hosts before plain "mailhost" and if that doesn't work, make 
sure mailhost is in the DNS.

You could also try "mailhost.example.com." (not the trailing dot) and 
the IP address for mailhost if nothing else works.

I don't know what your error is, I'm just going through the list of 
things I'd try if smart-host forwarding wasn't working.
