Abstract
Secure safe sender lists are described. In an implementation, a method includes examining a message received from a sender via a network to determine which identifying mechanisms are available for verifying an identity of the sender. When one or more available identifying mechanisms are deemed sufficient to verify the identity, a description of the identity and a description of the one or more said available identifying mechanisms are added to a safe senders list.
Claims13
A method comprising:
- examining a message received from a sender via a network to determine which identifying mechanisms are available for verifying an identity of the sender;
- determining that one or more available identifying mechanisms are deemed sufficient to verify the identity;
- in response to determining that one or more available identifying mechanisms are deemed sufficient to verify the identity, adding a description of the identity and a description of the one or more said available identifying mechanisms and an email address to a safe senders list;
- filtering the message by taking a form of a weight for adding an absolute reduction in a probability calculation assigned the message;
- processing the filtering of the message based on a form and a magnitude of the filtering by increasing or decreasing a probability that the message will be considered a spam;
- accessing the safe senders list which includes a combination of the email address with an available identifying mechanism, wherein the available identifying mechanism comprises a third-party certificate;
- and
- verifying the message from the combination of the email address signed with the third-party certificate, when there is a verification, the message is routed to an inbox;
- wherein the said available identifying mechanisms are deemed sufficient through comparison with the one or more identifying mechanisms identified in a list, wherein one or more of the available identifying mechanisms confirm the identity of the sender without utilizing the sender's address;
- and
- wherein the list references the combination of the one or more identifying mechanisms and another identifying mechanism.

- verifying an identity of the sender of the message;
- providing a result of the verifying and the message to a filter module for processing utilizing one or more spam filters;
- filtering the message by taking a form of a weight for adding an absolute reduction in a probability calculation assigned the message;
- and
- processing the filtering of the message based on a form and a magnitude of the filtering by increasing or decreasing a probability that the message will be considered a spare;
- accessing a safe senders list which includes a third-party certificate;
- and
- verifying the identify of the sender based on the third-party certificate, when there is a verification, the message is routed to an inbox.

A system comprising:
- a memory;
- a processor coupled to the memory;
- a first module that is executable on the processor to verify an identity of a sender of a message communicated via a network;
- a second module that is executable on the processor to process the message utilizing:
- one or more spam filters, and
- a result of the verification from the first module;
- a filter module that is executable on the processor to filter the message by taking a form of a weight for adding an absolute reduction in a probability calculation assigned the message;
- wherein the filter module filters the message based on a form and a magnitude of the filtering by increasing or decreasing a probability that the message will be considered a spam;
- wherein the first module checks for a third-party certificate included in the message, the third-party certificate involves a signing of a portion of the message with a certificate traced to a third-party certifier;
- wherein the first module verifies the identify of the sender by determining a level of security for the third party certificate comprising at least one of a reputation of the third-party certifier, a type of certificate, or an amount of the message signed;
- wherein the first module utilizes a plurality of identifying mechanisms that are suitable for confirming the identity of the sender without utilizing the sender's address;
- and
- wherein the first module uses a list describing a plurality of identifying mechanism combinations, that when satisfied, verify the identity of the sender.
