Another possibility is to run milter-greylist as root, then
you can have this:

drwx------   2 root  wheel   512 Feb 13 12:50 /var/milter-greylist
-rw-------   1 root  wheel  8331 Feb 13 12:50 greylist.db
srwx------   1 root  wheel     0 Nov  4 04:43 milter-greylist.sock

Of course, if you run milter-greylist as root, it is strongly
recommended to put it into a jail (like those supported on
FreeBSD) or similarly restricted environment, or use MAC
(mandatory access control) with appropriate policy if your
OS supports it.  (I do not recommend to use ordinary chroot
environment because it is too weak.)

Best regards

It's trivial to make fun of Microsoft products,
but it takes a real man to make them work,
and a God to make them do anything useful.
