This list has about 40k domains on it. We still looking for ways to prune it down, for example by expiring domains that no longer resolve. If someone had a reliable master list of expired domains, that could be very helpful.

    I have a list of dead domains on the sa-blacklist processing

system. Those are domains that were once on sa-blacklist, but removed because they either expired or were disabled by their registrar. I have a static version of the directory listing and will send that in a separate email to Jeff and Yusuf.

I have removed Bill's list of dead domains from all SURBLs. That should reduce all lists in size somewhat. Thanks much for sharing this resource Bill.
