An occasional individual blacklist lookup failure is not a problem, and is
rare (except for b.barracudacentral.org). I have not felt the need for
postscreen but of course it is a good tool: I prefer to block by ip last
and to log helo, envelope sender & recipient as well as client ip. This
puts a little more load on the server, but information is power.
