Milter-greylist

How do I get a custom report for a racl whitelist?

When I use this configuration line:

racl whitelist addr 24.24.2.48/28 spf report "SPF_OK From rr.com" 

the mail logs show:

Sep 19 07:32:31 host milter-greylist: l8JCWUF4004730: skipping 
greylist because address 24.24.2.56 is whitelisted, sender is SPF-
compliant, (from=<xxx@...>, rcpt=<xxx@...>, addr=ms-smtp-
02.nyroc.rr.com[24.24.2.56])

but I don't get a Milter add: header: X-Greylist: entry.
