Might try a package listing to see where it went:

  # pkg_info -L milter-greylist-1.5.6 (or your version)
  Information for milter-greylist-1.5.6:

  Files:
  /usr/local/man/man5/greylist.conf.5.gz
  /usr/local/man/man8/milter-greylist.8.gz
  /usr/local/bin/milter-greylist
  /usr/local/etc/mail/greylist.conf.sample
  /usr/local/etc/rc.d/milter-greylist.sh
  /usr/local/share/doc/milter-greylist/README
  /usr/local/share/examples/milter-greylist/greylist.conf

You can see that greylist.conf.sample was put (strangely) in
/usr/local/etc/mail. I copied this to greylist.conf and changed some
things like adding some 'addr' and 'rcpt' entries as needed, changed
"report all" to "report delays", "greylist 1h" to "greylist 5m",
"autowhite 3d" to "autowhite 30d", enable lazylaw, enabled dumpfreq
and timeout.

Greylisting works on the idea that much spam comes from "fire and
forget" spambots (usually Windows connections on broadband that have
been trojaned by some virus). Greylisting checks the envelope sender,
incoming ip, and envelope recipient; if that same triplet (tuple) has
been seen before, the mail is allowed through (to the next set of
checks), otherwise milter-greylist says "come back later" and records
the tuple.  Legitimate SMTP server always resend while most trojaned
spam-bots do not.
