Actually, you have to give it the directive to accept mail for the
domain and if you play it by the rules, you would edit (depending upon
your version of sendmail - this will refer to 8.10 or higher)

/etc/mail/local-host-names so that it accepts mail for listed names...

for example - my file reads

azapple.com
barney.azapple.com
localhost

Edit the file - restart sendmail (knowledgable people can tell you what
to HUP), I take the Redhat path of little resistance - service sendmail
restart

YMMV
