Another tip from the SBL folks:

> I'm not even sure where the root SBL zone server is.  All the public zone

> close-by servers when possible.)  Check "NS" records for
> "sbl.spamhaus.org".

> Probably goes without saying, but selecting a zone name that can be "end
> of lifed" when needed should be considered.



Also, someone else mentioned that the top-level zone, "surbl.org" for
example, may become the target.  So that also needs 2ndaries.
