ABSTRACT:
A system and method for sending encrypted messages to a distribution list that facilitates the sending of such messages only to individuals or other entities associated with the distribution list that will be able to read the message. In one embodiment, the method comprises the steps of: identifying a distribution list address in a message; determining one or more member addresses associated with the distribution list address; for each member address, determining if a public key for a member identified by the respective member address is available on the computing device; encrypting the message to each member identified by the one or more member addresses for which a public key for the respective member is available on the computing device; sending the encrypted message to the distribution list address if each of the one or more member addresses associated with the distribution list identifies a member for which a public key is available on the computing device; and sending the message to each of the one or more member addresses that identifies a member for which a public key is available on the computing device otherwise.
