I use milter-greylist. The ACL syntax is quite nice.

In the newer betas you can even greylist based on RBLs, and default to not
greylisting.

While this might seem an odd setup, think of how this could let you use RBLs
that are too aggressive for blacklisting, while not causing a lot of mail delay
for legitimate mail.
