It does occasionally affect legit mail; I'm dealing with one that is
apparently tickling the EXIM problem mentioned on the website.  But I
also just installed the qgreylist version (http://www.jonatkins.com/qgreylist/)
on a site running qmail, and "concurrency" dropped from 50-60 processes
delivering mail to keep up to 18.  It's well worth the occasional glitch.

One thing different is that qgreylist only uses the ip address, and uses
the filesystem as the database: essentially "touch ip-address" and then
check the file timestamp.  I modified it to make a path out of the ip
address to keep the directory from getting too large, but it's way
simpler and I don't think you're going to get spam and legit mail from
the same ip address.  certainly not for very long.

To announce that there must be no criticism of the President, or that we
are to stand by the President, right or wrong, is not only unpatriotic
and servile, but is morally treasonable to the American public.
-Theodore Roosevelt, 26th US President (1858-1919)
