If you have reliable DNS services - I've been on the other end of
that, a site permanently rejecting each mail (a 5xx code) because they
were having problems resolving the sending domain. Delegation and the
nameservers were fine, as it was the second address I tried (which
also failed with a 5xx code)

Very messy, and not very good for their customers.
