1. A method for operation upon one or more data processors to filter communications based upon content based policy compliance, the method comprising:
- for each of a plurality of sets of pre-existing files, defining a corresponding classification to be associated with the set of pre-existing files, the corresponding classification classifying content of the set of files as being associated with at least one of a plurality of departments of a business;
processing each of the sets of pre-existing files by one or more classification techniques;
generating a set of identifying characteristics for each corresponding classification, each set of identifying characteristics based on the set of pre-existing files associated with the corresponding classification;
for each of the plurality of corresponding classifications, receiving a rule specifying treatment of content identified as associated with the classification based on the set of known identifying characteristics; and
wherein each rule defines whether to forward a communication including content to a recipient based upon the classification of the content and at least one of the recipient and the sender.

24. A content-based policy compliance system configured to filter messages based upon content and at least one of senders or recipients associated with the messages, the system comprising:
-
a messaging content classifier configured to; access a plurality of sets of pre-existing files and for each set of pre-existing files define corresponding classification to be associated with the set of pre-existing files, the corresponding classification classifying content of the set of files as being associated with at least one of a plurality of departments of a business; processing each of the sets of pre-existing files by one or more classification techniques; generating a set of identifying characteristics for each corresponding classification, each set of identifying characteristics based on the set of pre-existing files associated with the corresponding classification; receive a message and classify the message as associated with at least one of the corresponding classifications associated with the business departments based upon the content of the message and the sets of identifying characteristics of the plurality of content classifications; a messaging filter configured to receive the at least one corresponding classification from the messaging content classifier and to apply a rule to the message based upon the at least one corresponding classification and upon at least one of a sender or recipient of the message; and forwarding logic configured to transmit the message responsive to output from the messaging filter. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31)

32. Computer readable storage media storing instructions that upon execution by a system processor cause the system processor to filter communications transmitted over a communication network based upon the content of a communication and upon the sender and recipient(s) of the communication, the media having stored instruction that cause the system processor to perform operations comprising:
-
for each of a plurality of sets of pre-existing files, defining a corresponding classification to be associated with the set of pre-existing files, the corresponding classification classifying content of the set of files as being associated with at least one of a plurality of departments of a business; processing each of the sets of pre-existing files by one or more classification techniques; generating a set of identifying characteristics for each corresponding classification, each set of identifying characteristics based on the set of pre-existing files associated with the corresponding classification; for each of the plurality of corresponding classifications, receiving a rule specifying treatment of content identified as associated with the classification based on the set of known identifying characteristics; and wherein each rule defines whether to forward a communication including content to a recipient based upon the classification of the content and at least one of the recipient and the sender. receiving a communication from a user, the communication containing an originating address, a receiving address, and content; determining whether the content of the communication substantially matches any of the corresponding classifications based upon the sets of known identifying characteristics associated with the corresponding classifications, respectively; and forwarding the communication responsive to the rule associated with the substantially matched corresponding classification, wherein the rule specifies an action to perform on the communication based upon the corresponding classification of the communication and upon the originating address and the receiving address of the communication.
