The community has a lightweight protocol which can be used for mail location
and delivery. It is called DNS. The tree structure used in DNS is almost
identical to that used in X.500, as are the procedures for navigation,
replication and distribution.

The major differences between X.500 and DNS are i) the provision of the
'attribute' data model in X.500 and ii) the more powerful operations
(such as modify) in X.500.

That DNS is not widely used for mail location/delivery(*) suggests
that there was actually a need for some of the complications in X.500.

(*) for users. DNS is, of course, used extensively to look up IP addresses :-).
