This is a silly reverse setup. A reverse lookup should only return one hostname, not 20.

Well, tend to agree.
What about the most stupid wanabe Spam-fighter which are very unhappy as in place (e.g. the third-party service provider systems acting with some SC subsidiaries...) which high rate valid messages if certain brain-dead conditions like PTR not matching MX don't match?
If this approach works out, it could be considered. It is not illegal. It's just against what we are used to over the last 20+ years. Just like the A records on second level domain names - depreciated some years ago, tough more and more common.
Under the line, it is likely not a DNS issue, but the inability by some mail or AS systems resolving lists. Suspect my servers will fail, too. Xaver, pls send private reply for a test from that system, anytime.
