The domain blocking list SURBL announced today that it is deprecating the SC (Spamcop) and AB (AbuseButler) sublists, migrating their data into a new ABUSE sublist. They note that the WS (Bill Stearns' sa-blacklist) sublist is also going to be migrated into ABUSE in 2016.
SURBL also recently announced the addition of SURBL-specific blocking notification messages to the popular SpamAssassin spam filtering software.
