Patent ID: 8019821

Claim:
A method for generating a distribution list prior to the transmission of information, wherein the generated list is based on the contents of information contained in a message destination field of a message containing the information to be transmitted, the method comprising the steps of: detecting and intercepting a message transmission attempt; identifying, from the contents of the information contained in the message destination field of the message, one or more sources of entrants for a distribution list; identifying one or more operations needed for generating a new distribution list from the contents of the information in the message destination field; generating the new distribution list based on the application of identified operations to the one or more identified sources of entrants according to a specified order of the identified operations; determining storage requirements for the newly generated distribution list, the storage requirements being based on contents of the information in the message destination field; and transmitting the intercepted message to entries in the newly generated distribution list, wherein said generating the new distribution list comprises performing mathematical, logical, and/or programmable operations, said logical operations including UNION and XOR set operations.
