[rbldnsd] Newbie questions

[Phoenix Kiula]

Thanks for this patient explanation. Very useful.

I think I need to rephrase my question.

With my /etc/resolv.conf already having 127.0.0.1, and BIND already
locally caching some results (as on Linux Cpanel it does), wouldn't I
get the local cache going even *without* rbldnsd?  I mean let's
presume I have NOT installed rbldnsd yet, and I have my
/etc/resolv.conf.

When I do this:

     dig a 36.94.21.46.sbl-xbl.spamhaus.org  @127.0.0.1

I already get the answer from the local cache, right? Even without rbldnsd?

(I recognize this may be out of the remit of a mailing list of
rbldnsd, but I am trying to ascertain if I need rbldnsd and would
appreciate your networking expertise.)

THANKS!
