"The PBL lists both dynamic and static IPs, any IP which by policy
(whether the block owner's or -interim in its absence- Spamhaus' policy)
should not be sending email directly to the MX servers of third
parties."
So Mike is right after all (the PBL isn't a list of dynamic IP
addresses), and so are you (the PBL lists *some* dynamic IP addresses);
at the same time you're both wrong because you're both excluding
information about both sets of data in order to make a point. Can we
stop arguing over semantics and look at reality instead?
Getting back to the OP's question, and your answer: Dynastop isn't doing
TXT lookups, because it's doing a different thing entirely. It might
reduce the number of TXT lookups for a given query, but that's because
it isn't doing DNS lookups at all.
But Mike already said that...
If anyone wants to comment further on the A & TXT lookup issue, be my
guest.
