No mail server should do that. It is quite common for mail servers to
relay mail from domains that don't correspond to them. For instance, many
of our customers relay their mail through outbound.sys.gtei.net, but our
mail server doesn't have the same address as their domain.

You shouldn't need to have multiple PTR records. All that should matter is
that the PTR record points to a name that points back to the original

If you really want multiple reverse entries, you should put them all in one
1 IN PTR host1.foo.org.
IN PTR host1.foo.hu.
