Sendmail and DNS on same server - Newbie question

This is behavior that I see on HP-UX and expected on Linux, as well.

However, with my RH 6.1, I noticed that this did *not* work for the
pre-linked network clients, like 'ping' and 'telnet' ('nslookup' *did*
work however, which is reasonable, since it doesn't use the resolver
libraries).

To make clients use the local nameserver, I had to add a "local"
nameserver line to resolv.conf:
    nameserver 0.0.0.0
or  nameserver 127.0.0.1
.

Yes.  This will make all programs use the local DNS, not just sendmail.

This is also what happens if you don't have any "nameserver" lines at
all
in the resolv.conf.
