Milter-greylist

I have the following lines in greylist.conf as a test:

racl whitelist from /@yahoo\.com$/
dacl blacklist from /@yahoo\.com$/ dkim none msg "Missing DKIM signature"
dacl whitelist from /@yahoo\.com$/ dkim pass addheader "X-DKIM: pass"

Logging shows that NONE of these hit on emails from yahoo.com. Tried both extended and non extended regex. Using milter-greylist 4.3.9

Not sure if the first line is really needed since default is whitelist for racl. The logging says that the email matched the last dacl rule, which is merely a whitelist that is after the 3 lines I provided here. The racl shows it matched the default racl whitelist line, which is also after the 3 lines shown here. So, even racl from did not match yahoo.com

Does it need a trailing > perhaps? What could be wrong?
