1. In a computer environment having a messaging service for transmitting messages created by clients having public key cryptographic support, a method for managing a crypto policy for messages submitted for transmission by the messaging service, the method comprising:

  • defining a crypto policy comprising a set of constraints specifying one or more conditions which messages submitted to the messaging service must satisfy before being accepted for transmission by the messaging service;

    receiving a particular message from a client for transmission by the messaging service;

    determining whether the particular message conforms to the crypto policy by applying said set of constraints to the message;

    if the particular message satisfies said set of constraints, forwarding the particular message to the messaging service, so that the message may be transmitted to its intended recipient; and

    if the particular message does not satisfy said set of constraints, rejecting the particular message, so that the message is blocked from transmission by the messaging service.
