Email Filtering Expert in Authorization Lists
An email filtering expert in the use of authorization lists to enhance computer security was needed for a patent infringement case involving internet based communications technologies. Plaintiff alleged the defendant infringed on patents covering methods and systems for filtering unsolicited electronic mail. At issue was whether the defendant's MTA, or mail transfer agent, products and services, which relied on reputation scores to filter spam email, encroached on plaintiff's email filtering patents.
