Briefly, we need to be able to turn on the feature "verify connecting hostname in DNS" as this defeats a lot of spam. However, because the D7/D8 whitelist feature does not currently take precedence over this, it isn't possible to make any exception for servers whose email we want but which, for reasons which are often outside of the control of their administrators, have broken or missing DNS.
This rules out the use of "veriify connecting hostname in DNS" (a very powerful anti-spam feature) at any site needing to accept email from selected systems whose DNS is broken, which would include a high proportion of legitimate senders in asia and the far east.
A more detailed explanation is here.
