Postfix
postfix sets the hostname of clients without a reverse dns mapping to
‘unknown’ — maybe milter-greylist should do the same:
postfix/smtpd[15288]: connect from unknown[42.34.51.23]
milter-greylist just takes what it gets and that's often:
milter-greylist: (unknown id): addr [42.34.51.23][42.34.51.23] (...)
Patch is attached. Once applied, clients without a reverse dns mapping
will trigger the SpamAssassin RDNS_NONE test.
