NetFrameworks, Inc., a security products and consulting services firm, on Friday said its researchers have discovered that leading spam blocking systems, including a top processor of email worldwide,
Yahoo!, are blocking email confirmations from the Federal Do Not Call Registry launched this morning by the Federal Trade Commission. "This highlights how difficult it is to control the flow of
unsolicited communications of any kind, be it phone or email," stated Eric Greenberg, NetFrameworks CTO and co-founder. "Current unsolicited communications detection and assurance mechanisms are based
on a set of arbitrarily defined rules. The people that control the rules, by definition, often know very little about what truly constitutes spam or unwanted solicitations."
