Good idea. RBLs are brilliant but when Vixie invented the idea and the
Apache SpamAssassin team implemented it some 2 decades ago, I wrote
something to the effect of what a (brilliant) hack. We need to replace
this with something in a year.
Now, many many years later and several DDOSes against RBL operators like
STORM network, the use of DNS for RBLs remains :-)

Thank you all who shared their knowledge.
We decided, on our solution, to go away from the DNSBL approach which
has way too many caveats and are now experimenting with solutions on a
higher level on the network stack.
