The code that's using SURBLs generally should only be looking at
message bodies, so it should only match on spam domains in the
message body URIs and not header info. 

That said, since Bill's data which ends up in ws has some sender
domains in it, using ws.surbl.org in conventional RBL code that
looks at message headers such as sender domain may get some matches.

However attempting to match sender domains would give far fewer
(near zero) hits with sc.surbl.org whose source data comes from
message bodies only.

In other words we're trying to use SURBLs on message body URIs
and not against message headers, which would be more like using
a regular RBL.  As I understand it Bill is also focusing on
adding URI domains to his list lately, which is a good match 
for the intended use of SURBLs.

Hope this helps,

Jeff C.
