An email security system is described that allows users within different organizations to securely send email to one another. The email security system provides a federation server on the Internet or other unsecured network accessible by each of the organizations. Each organization provides identity information to the federation server. When a sender in one organization sends a message to a recipient in another organization, the federation server provides the sender's email server with a secure token for encrypting the message to provide secure delivery over the unsecured network.

A lock associated with the throttle condition may be created on the message until the throttle condition is satisfied. Then, the lock on the message may be removed and the message may be delivered.
