Messaging enhancements
In some embodiments, techniques for electronic messages may include various enhancements.
1. A method for updating a whitelist, comprising:
receiving a change of address directive;
wherein the change of address directive includes a new address;
determining whether the change of address directive is authentic; and
adding the new address to the whitelist, if it is determined that the change of address directive is authentic.
2. The method of claim 1 , wherein the change of address directive is associated with an email.
3. The method of claim 1 , further comprising removing an old address from the whitelist.
4. The method of claim 3 , wherein the change of address directive includes the old address.
5. The method of claim 1 , wherein the new address is a hash of a second address.
6. The method of claim 1 , wherein determining whether the change of address directive is authentic includes determining whether the change of address directive is associated with an authorized change-of-address authority.
7. The method of claim 1 , wherein the change of address directive includes a token, and wherein determining whether the change of address directive is authentic includes determining whether the token matches a stored token.
8. The method of claim 7 , wherein the change of address directive is associated with an old email address, and wherein the stored token is associated with the old email address.
9. The method of claim 1 , wherein determining whether the change of address directive is authentic includes verifying a cryptographic signature.
10. The method of claim 1 , wherein determining whether the change of address directive is authentic includes verifying an email sender, wherein the email sender is associated with the change of address directive.
11. A system for updating a whitelist, comprising:
a processor configured to:
receive a change of address directive;
wherein the change of address directive includes a new address;
determine whether the change of address directive is authentic; and
add the new address to the whitelist, if it is determined that the change of address directive is authentic; and
a memory coupled with the processor, wherein the memory provides instructions to the processor.
12. The system of claim 11 , wherein the change of address directive is associated with an email.
13. The system of claim 11 , wherein determining whether the change of address directive is authentic includes determining whether the change of address directive is associated with an authorized change-of-address authority.
14. The system of claim 11 , wherein the change of address directive includes a token, and wherein determining whether the change of address directive is authentic includes determining whether the token matches a stored token.
15. The system of claim 11 , wherein determining whether the change of address directive is authentic includes verifying a cryptographic signature.
16. A computer program product for updating a whitelist, the computer program product being embodied in a computer readable medium and comprising computer instructions for:
receiving a change of address directive;
wherein the change of address directive includes a new address;
determining whether the change of address directive is authentic; and
adding the new address to the whitelist, if it is determined that the change of address directive is authentic.
17. The computer program product of claim 16 , wherein the change of address directive is associated with an email.
18. The computer program product of claim 16 , wherein determining whether the change of address directive is authentic includes determining whether the change of address directive is associated with an authorized change-of-address authority.
19. The computer program product of claim 16 , wherein the change of address directive includes a token, and wherein determining whether the change of address directive is authentic includes determining whether the token matches a stored token.
20. The computer program product of claim 16 , wherein determining whether the change of address directive is authentic includes verifying an email sender, wherein the email sender is associated with the change of address directive.
