even when running in pure greylisting mode, i get almost no spam

only thing worth watching for is organizations that use their email as a
short lead-time communication method. in this case people will call and
say "where is my email from new client X!" and you have to either
manually whitelist or tell them what they don't want to hear "well, you
have to wait 25 minutes or more for their server to be whitelisted".
Just say that you are investigating it, and take 25 mins over your
"investigation" (surf for pictures of enema discharges to send to them),
tail the logs, and let them know that the host is now white listed. Job
done.
that's a shitty suggestion =).
for domains that have multiple MX records, it might be nice to have all
those IPs whitelisted when sending to that domain. maybe this is already
done or there is a reason it isn't :). guess someone could publish a
list of bogus IPs in their MX records...

confusion <blush>.
Can be used to weight spam assain
