Method and system for sorting and prioritizing electronic mail messages

1. A system for prioritizing by an individual user a plurality of messages directed to and received by a preidentified user of an electronic mail system comprising a message store for storing received messages directed to the user; rules control means operable by the individual user for creating a plurality of individualized user-defined rules for prioritizing received messages in accordance with criteria selected by the individual user; means for storing said user-defined rules; rules testing and priority assigning means for automatically applying said user-defined rules to each message in the message store thereby assigning to each message a priority within a predetermined range of priorities selected by the user; and means responsive to assigned message priorities for selectively routing each message to a main message folder for later presentation to the user in order of said assigned priority.

2. The system of claim 1, wherein each message comprises a plurality of fields, each field containing information of a predetermined type, and wherein the rules testing means includes means for comparing information in one or more of such message fields with criteria embodied in said user-defined rules thereby assigning a priority to a message.

3. The system of claim 2, wherein said message store comprises a plurality of message storage units, one associated with each message, the message storage units each having a plurality of regions corresponding to the plurality of fields in each message for storing in such regions information contained in the corresponding fields of each associated message, and wherein said rules testing means compares information stored in predetermined ones of such regions with selected criteria embodied in said user-defined rules.

4. The system of claim 3, wherein each of said user-defined rules comprises a first part which includes conditions specified by said criteria which are applied to each message and a second part which specifies actions to be taken upon a message matching the conditions in the first part.

5. The system of claim 4, wherein the conditions include the identity of a message sender, the number an identity of addressees of a message, and keyphrases which may be contained in an address or text within a message.

6. The system of claim 4, wherein each second part specifies rules testing means for assigning a priority code to a message in response to the results of the comparing of the information in message fields with conditions in the first part of the rule, and means for directing a message to other users and to files which may be used by other users.

7. The system of claim 2, wherein the rules testing means includes means for applying user defined rules to stored messages in a preselected sequence, means for storing the results of a partial application of said sequence, and means automatically for varying the sequence in which the remaining user-determined rules are applied to each message in response to said partial results.

8. The system of claim 1, wherein the means for selectively routing messages to the main message folder comprises means for arranging messages within the folder in order of priority such that messages having the highest priority are presented to the preidentified user first.

9. The system of claim 1, wherein the rules control means includes means operable by a user for modifying previously created user-defined rules stored in said rules storing means.

10. A method of prioritizing a plurality of messages directed to a user of an electronic mail system comprising the steps of storing messages directed to the user in a message store; prioritizing the stored messages in accordance with criteria selected individually by the user by automatically applying to each of the stored messages a plurality of individualized user-defined rules thereby, assigning to each stored message a priority; and selectively routing each of the stored messages to a message folder of the user for later presentation to the user in order of assigned priority.

11. The method of claim 10, wherein each message comprises a plurality of fields which contain information of predetermined types, and wherein said applying comprises comparing information in one or more of such message fields with criteria embodied in said user defined rules, thereby assigning a priority.

12. The method of claim 11, wherein said storing comprises storing information contained in message fields in regions of the message store corresponding to such fields.

13. The method of claim 12, further comprising the step of acting upon each of the stored messages in predetermined ways depending upon the results of such comparing.

14. The method of claim 13, wherein said predetermined user has a plurality of folders in said electronic mail system, and wherein said acting comprises forwarding each message to other users and to selected ones of said plurality of folders of the preidentified user.

15. The method of claim 13, wherein the information in the message fields which is compared to the criteria embodied in said user defined rules include the identity of a message sender, the number and identities of addresses of a message, and keyphrases contained within a sent message.

16. The method of claim 15, wherein said applying is done sequentially, partial results are stored and any remaining results may be automatically controlled in response to said partial results.
