No, the DNS setup on the sending side is broken.

If one out of "x" DNS servers claim there are no entries for "domain",
there's a one in "x" chance the receiving side talks to this particular
DNS server and is getting a wrong answer.

The receiving side is told there is no MX record and no A record.
Their test is OK.
