reject-missing-sender-mx Check the domain name of the sender's email address for a mail exchanger (an MX or an A record). If neither are found, reject the connection. Maybe you had authenticated for this test, in which case it would be let through? It definitely works - I see rejections every day, usually for bank phishing emails from non-existent domains, or from badly configured list servers where lists.domain.com has no MX record. Faris.
