Add this to /etc/mail/sendmail.mc, then run make in the same directory. FEATURE(accept_unresolvable_domains)dnl
But are you sure you need this? If you just want this particular address to resolve, just stick it in your /etc/hosts file and make sure your /etc/mail/service.switch file has the line hosts files dns which tells it to look at the hosts file before querying DNS. Removing the "dns" from this file also stops DNS lookups completely.
