See http://harishpillay.livejournal.com/44948.html.  I have been using
milter-greylist since late 2006 early 2007 and all I can say is that
spam has been reduced to less than 1% of what it used to be.

I don't use spamassasin or any other filters for greylisting does
it very well for me.

I am running that on a machine that receives mail for a domain
that has about 10K users and ever since it was turned on over
3 years ago, the user base has been very happy.

BTW, the system is running on a Fedora 13 system right now
but started life on a Fedora 7.

Regards.
