Sendmail will be happier if dns is working
completely - you may want for other reasons
as well to make your gateway also run a
caching dns server. It can be authoritative
for your small domain and a forwarder for
everything else -

Use a fully qualified domain name in sendmail.cf -

Here is the area of interest in /etc/mail/sendmail.cf
# my official domain name
# ... define this only if sendmail cannot automatically determine your 
domain
#Dj$w.Foo.COM

Edit the Dj line to use your full hostname, e.g:

Djbonsai.mydomain.net

Be sure and use a legitimate hostname or your
mail will be bounced by many mail servers.
