SECURING RELAYED EMAIL COMMUNICATION

Disclosed are systems and methods that facilitate encryption of email messages that are transported between mail servers. In some cases, email messages may be relayed through relay mail servers as well. An email message can be encrypted using a public key that corresponds to an organization associated with the recipient rather than a public key associated with the particular recipient. The email message can then be decrypted by the recipient mail server and deposited into a mailbox of the recipient.
