Good to know. As of 4.22, that behavior is apparently documented
only in the description of $host_lookup. It would be more "visible"
if it were mentioned in the description of $sender_host_name itself.
It also should probably be mentioned, at least by reference, in
section 10.11.

What does that mean? That if there are multiple PTR records all the
corresponding A records are checked?
