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.

I use postfix and sqlgrey for greylisting at all of my
clients/installations and it's incredible but I still use MailScanner
(
http://www.mailscanner.info) which provides a wrapper for spamassassin
& clamav. Even with greylisting, spamassassin will still identify spam
coming through. I had no specific complaints about sendmail but I find
the features much more easily accessible in postfix.
