	No.  You don't need a nameserver on the machine for this function.

	Change your /etc/resolv.conf to point to other 
recursive/caching-only servers, and have other 
authoritative-only/non-recursive servers set up to serve the domain. 
Then turn off named on the local machine.

	Moreover, I would submit that you should probably have people 
delivering directly to the appropriate mail server, and not routing 
through the Unix box.  If there is a good reason for doing this, then 
you want the simplest possible configuration, and the FAQ at 
<http://www.sendmail.org/faq/> should be able to help you with this.

	Which version of BIND are you running?  If it's not at least 
8.2.4-REL or 9.1.2-REL, then you should upgrade.

	If you're running BIND 9, you should have the tools 
named-checkconf and named-checkzone.  You should run these two 
utilities on your /etc/named.conf and your various zone files, 
respectively.  If they come up clean, then named should load them 
okay.  There may be other issues keeping things from working quite 
right, but at least named should load them.

	If you want to look at these other issues, you should run "doc" 
and "dnswalk" on these zones.
