This is similar conceptually, although not nearly as draconian, as rejecting

Best guess tries to assume that there is some relationship between the IP
address of a legitimate sending mail server and either the MX or the web
server for a domain. While this may often be true, there is no basis in
internet standards to make that type of assumption.
Yes, but keep in mind this is just the fallback. If they don't like my
default, they're free to publish another, and that could even be "+all".
(which is explicitly telling me they don't mind forgeries, and will get them
eventualy blacklisted, of course ;).
