Abstract
A method of validating queries for reputation scores of message senders comprises receiving, from a first host computer, a DNS format query to obtain a reputation score associated with a second host computer, wherein the query includes an authentication code; validating the authentication code; and only when validating the authentication code is successful, performing a DNS lookup in a reputation database and returning a DNS response that provides the reputation score associated with the second host computer.
