I don't understand. The score of this message is exactly 5. And since 5
is not >5, the message gets queued.

There is a difference between spamd and milter-greylist when it comes to
the decision, whether a message is spam or not. The former decides based
on the required_score threshold in local.cf and the latter based on
dacls in greylist.conf. Therefore, even if spamd considers the message
as being spam does not necessary mean that milter-greylist thinks the
same and since it's milter-greylist who decides, the reported result by
spamd is irrelevant.
