This suggest there is no need of separate certificates for separate
domains. I think that would address TLS side of it.

The thread is having relatively less discussion on TLS, but more on the
tactics the mail servers (particularly the dominant players) apply to
control spam (or so they say) - one of which is that they check reverse
dns map between your ip and email domain.

And because of such check would such setup work (work in the sense of
acceptance by mail servers at large and if possible reducing the chances
of them marking it spam).
