A quick thought here- RBL uses an A record type lookup-
somewhere.nasty.com gives 127.0.0.2 (scumbag)- these are nice small (UDP)
queries. Whereas SPF has to look up a TXT record to get the SPF string-
could these be going over the UDP limit? Could TCP based DNS queries be
blocked or just the TXT lookup?

I have that every day- I don't "own" any of the networks I admin, does make
for fun.
