Updating hierarchical whitelists
View Patent ↗A system and method are disclosed for maintaining a whitelist, including: obtaining message data based on an email message sent by a user; extracting recipient information from message data; updating the whitelist using the recipient information.
1. A system for updating a plurality of hierarchal whitelists, comprising:
a messaging software application stored in memory and executable by a processor to:
access an e-mail message to obtain message data associated with the e-mail message sent by a sender to a recipient in a network,
extract sender information and recipient information from the message data,
send the message data to a server; and
a server device to update a plurality of whitelists residing on the server to add the extracted recipient data, the whitelists associated with:
the sender, wherein the recipient is identified as being allowed to send e-mail messages to the sender, and
a group of users that share whitelist entries, wherein the recipient is identified as always being allowed to send e-mail messages to the group of users.
2. The system of claim 1 , wherein the message software application resides on a firewall that monitors and logs network activities associated with outbound e-mail activities.
3. The system of claim 2 , wherein the message software application extracts recipient information from the message data based on firewall log messages associated with outbound e-mail activities.
4. The system of claim 1 , wherein the server device automatically updates the plurality of whitelists.
5. The system of claim 1 , wherein the message software application resides on the server device.
6. The system of claim 1 , wherein the message software application resides on a mail client.
7. The system of claim 1 , wherein the message software application is executable to access an e-mail message by reading a database of sent messages.
8. A method for updating a plurality of hierarchical whitelists, the method comprising:
accessing an e-mail message to obtain message data associated with the e-mail message sent by a sender to a recipient in a network,
extracting sender information and recipient information from the message data,
updating a plurality of whitelists residing on a server to add the extracted recipient information, the whitelists associated with:
the sender, wherein the recipient is identified as being allowed to send e-mail messages to the sender, and
a group of users that share whitelist entries, wherein the recipient is identified as always being allowed to send e-mail messages to the group of users.
9. The method of claim 8 , wherein the sender is a trusted user.
10. The method of claim 8 , wherein the whitelists are further associated with a corporate group that maintains addresses that are applicable to any user or other group within the corporate group.
11. The method of claim 8 , wherein the whitelists are further associated with a global whitelist that allows certain addresses to be whitelisted.
12. The method of claim 8 , wherein the plurality of whitelists are automatically updated.
13. A non-transitory computer-readable storage medium having embodied thereon a program, the program being executable by a processor to perform a method for updating a plurality of hierarchical whitelists, the method comprising:
accessing an e-mail message to obtain message data associated with the e-mail message sent by a sender to a recipient in a network,
extracting sender information and recipient information from the message data,
updating a plurality of whitelists to add the extracted recipient information, the whitelists associated with:
the sender, wherein the recipient is identified as being allowed to send e-mail messages to the sender, and
a group of users that share whitelist entries, wherein the recipient is identified as always being allowed to send e-mail messages to the group of users.
