more questions on rbl

[Mate Wierdl]

At the expense of sounding like an idiot:

Why are all these complications of DNS queries are used to find out if
a certain IP is in a server's rbl database?  Are DNS queries processed
faster than finger's or qmail-lspawn's when it uses qmail-users ?

In what sense is it advantageous to require the delegation of a whole
DNS domain to handle rbl database lookups?  Afterall, we are just
talking about a list of (IP)numbers to search, and not some
complicated records.
