This is a bug.

yes rbldnsd "prefers" everything in lower case, but that's
just because it lowercases everything, or, rather, is supposed
to.

The only place where it is NOT done is while parsing the command
line - generating list of zones to serve.  I just forgot to
lowercase the whole thing.

The fix (one-line patch) is below.

Now I'm really curious why it took so many years to find
the damn thing...
