Thanks for a good response Matt!  You hit all the points

Key is that SURBLs contain message body URI domains.  This is
a very different approach from most RBLs which as you note list
sender domains or sending IP addresses.   SURBLs don't go after
the sources of the messages, they go after the URIs in the
message bodies.

The enumerable domains in be.surbl.org are now being merged into
ws.surbl.org, so be.surbl.org is just about ready to go away,
with the heavily-wildcarded, widely-varying domains ending up
exclusively in BigEvil.cf.

In other words the domains from BigEvil and MidEvil that can be
listed without many wildcards go into ws.surbl.org and the
domains that need more wildcards (too many to be practically
enumerated) will end up in BigEvil.cf .

Chris may not be ready to do the latter yet, but the former is
already in place as of a few days ago.  We're watching it all
run for a while before announcing officially.
