question with greylisting

[Paulo Roncon]

Hello, 

I've installed the rpm milter-greylist and i'm running it.
The only messages that I see in my maillog are:

May 30 17:14:12 papagaio sendmail[5158]: n4UGE76o005158: Milter add: header: X-Greylist: Default is to whitelist mail, not delayed by milter-greylist-3.0 (localhost.localdomain [192.168.89.11]

I'm I doing anything wrong? It dont seens that its doing anything... I've used the guide in the maillscanner site.
Can you post a sample config?

thanks
