  • Patent number: 10116609
    Abstract: Technologies are described related to third party email signature generation and authentication. A DKIM signature may be stamped in a way such that the “From” address is encoded in the selector. The domain may be extracted from the DKIM signature based upon being from a known sender in the d=field, which signs on behalf of another domain. The reconstructed domain may be aligned from the selector against the actual domain in the “From” address to pass DMARC.
    Type: Grant
    Filed: November 8, 2015
    Date of Patent: October 30, 2018

  • Patent number: 9116879
    Abstract: Embodiments are directed to generating a customized classification rule execution order and to identifying optimal ordering rules for previously processed data. In an embodiment, a computer system fingerprints a message received via a computer network. The fingerprinting identifies specific characteristics of the message. The computer system compares the message's fingerprint to various stored message fingerprints generated from previously received messages. The comparison determines that the fingerprint does not match the stored fingerprints. The computer system applies classification rules to the message according to a predetermined rule execution order to determine a classification for the message. The computer system then generates a customized classification rule execution order to order those classification rules that optimally identified the message's class at the top of the customized classification rule execution order.

  • Patent number: 7756929
    Abstract: The present invention provides an improved system and method for processing e-mail. The system may be implemented over a distributed network having several redundant mail servers. The system may include a message switch that receives all incoming e-mail messages and includes a policy filter, a content filter, a virus filter and a spam filter. The filters process the message in a sequential order and can be dynamically reconfigured to adapt to certain conditions. The message is stored in an area of the message switch and the filters communicate with each other by passing links to the message in order to reduce input/output. This communication method may be altered to suit the installation of the software, without altering each filter. Messages that do not pass the filters may be rejected or placed in a quarantine area. Messages that pass all of the filters are delivered to their intended recipients.
