what are you using to greylist based on blocklists?
I use maRBL. The latest version lets me greylist (I use sqlgrey, but
there are others) anyone who is found on whatever RBLs I configure it
to check, and any connection that comes from a Windows box (the vast
majority of which are botnet zombies). It has had an immense impact on
the amount of spam that gets through to be looked at by SA & clamav.
I've been very happy with it.
