At dnswl.org <http://dnswl.org/> we check our data against the DROP list every once in a while. The overlap of DROP with legitimate sources of SMTP traffic is very, very small: a low single-digit number, and most of them are crappy to start with (so we don’t publish them, but only keep them in our database for reference purposes). — Matthias

How much false positives (i.e. blackholing traffic users want to reach)?

Any ISPs out there (big or small) ever used the Spamhaus BGP feed to prevent against botnet, spam, etc? If so, how has your experience been? Is it worthwhile? Has it helped? On / off list responses are appreciated in advance. We use Spamhaus DROP (not the BGP version: our software asks a human to review each change). The benefits are not obvious since we do not have access customers, but it will blackhole some networks you obviously do not want to talk to, and it has not caused any troubles either.
