I have seen some listings on spamhaus as Spamhaus Botnet C&C (BGPCC) List See for eg. http://www.spamhaus.org/sbl/query/SBL140862
( This listing is available at least for now ) What is this .. a new list ? What is the criteria for listing ? Do I include lookups for these too in scoring my mails in spamassassin ? Thanks Ram
