http://www.postfix.org/postconf.5.html#parent_domain_matches_subdomains

parent_domain_matches_subdomains (default: see postconf -d out-
       put)
       What Postfix features match subdomains of "domain.tld"
       automatically, instead of requiring an explicit
       ".domain.tld" pattern. This is planned backwards compati-
       bility: eventually, all Postfix features are expected to
       require explicit ".domain.tld" style patterns when you
       really want to match subdomains.
