braindead argumentation because it was a technical problem until you 
stepped in

when i try to reduce the amount of dns-queries to the service to reduce 
their load because i decide for me that instead 5 seconds 30 or 90 
second are "realtime" the R in RBL enough

frankly, even *if* i pay for the service i would call it a good citizen 
to produce less load and the "minimum-ttl" also reduces load from other 
RBL's without any restriction

additionally you can *not* control your inbound mailflow - so when the 
same IP is hammering on your server and you produce 20 times mor DNS 
requests than the rest of the year what options do you have - you did 
nothing wrong and exceeded limits
