I think what Matus was saying is:

And what I'm saying is that the second step of that:
"localhost" -> 127.0.0.1
doesn't work since "localhost" has no A record.
So that data comes from /etc/hosts. How does that materially affect the
FCrDNS sanity test?
So it should actually go:
181.188.252.222.in-addr.arpa -> "localhost" -> FAIL
and I'm not sure if that result nulls the equation or if it actually
outputs an FCrDNS failure. My guess is that it does. YMMV by MTA.
You're treating "localhost" as a special case of FCrDNS. While that's
reasonable, you shouldn't have to do that. If you don't have "localhost"
in the /etc/hosts file on a production machine you shouldn't be an
admin... (<-- sweeping generalization, I know.)
