And only when one's transport table or relayhost specifies a
nexthop of the form:

        [gateway.example.com]

does the TLS policy table need an entry of the same form:

        [gateway.example.com]   encrypt|secure|fingerprint ...

For "[gateway]" nexthops there is no real difference between "secure"
and "verify", both test for the same nexthop address, unless "match"
values are specified explicitly.

In retrospect, it an interface design error to provide both levels,
just one would have been enough, with backwards compatibility for
tls_per_site provided via different "match" values for "verify" not a
different security level.  Both, verify certificates using a slightly
different default set of match values. :-( The "damage" is fairly minor...
