But ill try to answer anyway. After 2 min. of googling: FEATURE(accept_unresolvable_domains). Normally, sendmail will refuse to accept mail that has a return adress with a domain that cannot be resolved using the regular host lookups. (a technique commonly used by spammers). This feature permits acceptance of such addresses. Unresolvable domains can be selectively accepted using the access database.
