  • Email policy manager
    Patent number: 8209538
    Abstract: An email policy is applied in a policy manager, running on a mail server in a local area network, to determine whether an outgoing email message should be allowed to be transmitted to a destination address outside the local area network, for example over the internet. A digital signature is used in the policy manager, to determine if the sender is the sender indicated in the message itself. If so, a sender-dependent policy is applied.
