1. A collaborative messaging system, comprising:

a communications engine executing in a microprocessor, comprising:

a plurality of message interrogators to process a message from a sender to a receiver, the message comprising message sender information and message content information, comprising:

a message adjudicator configured to:

compare message information from the sender with message information obtained by the message adjudicator, the obtained message information comprising message sender information, message receiver information, and message content information;

modify the message information from the sender to a higher classification level of the message sender information from the sender and the obtained message sender information;

further modify the message information to a higher classification level of the message content information from the sender and the obtained message content information; and

filter the message content based upon the further modified message information and the obtained receiver information; and

a message validator configured to allow or deny the message based upon the further modified message information and the obtained message receiver information.

2. The system of claim 1 , wherein the message adjudicator filters the message content by removing classified material from the message content.

3. The system of claim 1 , wherein the message adjudicator filters the message content by removing offensive material from the message content.

4. A collaborative messaging method, comprising:

in a communications engine executing in a microprocessor, processing a message from a sender to a receiver, the message comprising message sender information, message content, and message content information, comprising:

comparing message information from the sender with obtained message information, the obtained message information comprising obtained message sender information, obtained message receiver information, and obtained message content information;

modifying the message information from the sender to a higher classification level of the message sender information from the sender and the obtained message sender information;

further modifying the message information to a higher classification level of the message content information from the sender and the obtained message content information;

filtering the message content based upon the further modified message information and the obtained message receiver information; and

allowing or denying the message based upon the further modified message information and the obtained message receiver information.

5. The method of claim 4 , further comprising modifying the message information from the sender to a lower classification level of the message sender information from the sender and the obtained message sender information.

6. The method of claim 4 , wherein the message sender information further comprises message sender classification information and the obtained message information further comprises obtained sender classification information, and further comprising:

modifying the message information to a higher classification level of the message sender classification information and the obtained sender classification information.
