Possibly, less so if sendmail is on the same machine as the local DNS
server. However, I would certainly make any machine that's directly
connecting to the Internet have a hostname that resolves globally and
not just locally. In Antonio's situation I would probably have just set
up an A record for machine.ourdomain.com with the same address as
ourdomain.com (not using "machine.ourdomain.com. CNAME ourdomain.com."
because the name that the machine knows itself as is
machine.ourdomain.com, not ourdomain.com, and not using "ourdomain.com.
CNAME machine.ourdomain.com." because there are no doubt MX records for
ourdomain.com and you can't have CNAME records coexisting with anything
else).
