I have several boxes that "check" my relay every 40 seconds to
check that the server is up.
After multiple attempts to get the number of checks reduced I would
like the know the preferred way to block specific IP addresses in Postfix.
I have no issue with checks.. but every 40 seconds is ridiculous.
the first answer is: try to reach their abuse/postmaster. if you fail,
then firewall them. if so, just DROP their traffic (this will cause more
delay on their side). you can also redirect their traffic to a "slow
silly server" ("torture server").
Mouss..
I could use a host based fw.. but would rather use Postfx as there
are only a handful of pollers..
