Questions about sendmail and name servers

[ROOT]

I'm new to this list but I heard that there is alot of talk about sendmail
and name servers. I am interest in running a version of sendmail on SunOs
3.5 and using a name server on another machine to resolves network
addresses. I know that SunOs 4.0 can handle this but I got to work with
3.5. Has this been done before ? Does anyone have a sendmail that use a
name server to resolve addresses and run on a untouched  SunOs 3.5 ?

Thanks
