Suggested Procedures:
We use a script that validate the blacklisted services for:
. reachability
. delay
. if any of our subnet is blacklisted
And we also run a named exclusivly for caching requests...
This way the mail system gets back on its feet by itself...
Queries to loaded BL service are temporary disabled automatically...
until the service become more responsive.
And we know, quite fast, if a client breach its contract and start
spamming...
Not every antispam system are that open... But if you have one...
It might be worth the 8 man hours to do a patch.
Have fun...

Anyone else having ORDB.ORG Temp lookup failures? Seems to have been
going on since about 1900 UTC today. Using web site to do lookups
also fails or is VERY slow.
Anyone know what is going on here?
THANKS!

We have had to do the same was slowing down a bunch of mail.
I do run my own caching name server on the same exact box as a matter of
fact. But I hear one of their servers is under DOS uttack but that is
nothing official, still awaiting word.
