I'm seeing a lot of false positives from SpamCop blacklisting Yahoo mail IP's.
For example: http://www.senderbase.org/senderbase_queries/detailip?search_string=98.138.82.0%2F24 http://www.senderbase.org/senderbase_queries/detailip?search_string=115.178.12.0%2F24 Anyone tried or anyone have a contact at SpamCop who can get Yahoo mail blocks whitelisted? - Julian
