Here's some additional info on some of the recent
sa-blacklist/ws.surbl.org/6dos goings on, copied from a
message I sent to the SpamAssassin-users list:

I think I can help explain why sa-blacklist went from 1.5 MB
to 5.5 MB in size suddenly.  Chris Santerre added a fairly large
set of records from 6dos (6 degrees of spam) around that time in
order to get the records into ws.surbl.org and sa-blacklist.
Chris, Bill and I then discussed this and decided to take them
back out of sa-blacklist and therefore ws.surbl.org, and put
the 6dos entries into its own SURBL instead.

However Bill's server experienced a hard disk problem around
the same time so the entries have not come out of sa-blacklist
yet.  But they will come out once Chris gets access to Bill's
server again.  Until then, backing off to an earlier version
of sa-blacklist makes perfect sense and it's what we've done
for ws.surbl.org.

When Chris gets in again, he will get the 6dos entries off
sa-blacklist, it will come back down in size, and I'll restore
live feeds of ws.surbl.org from the sa-blacklist data instead
of freezing it at the older version, as it is now.

Hopefully this makes some sense.  If not I'll glady try to
answer any questions or comments anyone has, though I'm not
the original source of the changes.
