I'm not in to Sendmail, but you might want to ask yourself if you really want to accept such mails. Usually, such mail are spam or virusses and if the domain does not resolve, can cause problems when those messages get bounced. If the mails are legitimate (very small chance), it means that there is a configuration error somewhere. A good sysadmin will pickup that a large portion of outgoing mail is refused with "Domain of the sender does not resolve". One other thing, you might want to check your DNS-server(s) and verify it's results. I've had a similar problem recently and it turned out the DNS-server was bricked.
