I used greylisting for a while, but I found too many
false positives
(for me) with sites that are "legit" but don't work with it. Generally
it seemed to be situations like big sites that would retry from one of a
cluster of MTA boxes.
Do you have any problems? Maybe the world has improved since I last
tried it.
Postgrey comes with some whitelisted exceptions for places like Google,
but they aren't the ones who are sending the spam.
There is one source I needed to whitelist myself, but they're the sort
of place that rejects postmaster@ email with 'no such user', sigh.
