Strange:

With "dig" we see the exact same thing.

However, in last week, our exim got a few hundred messages from this IP,
and the logs imply it was always able to get a hostname (2-way match
succes), which seems a bit odd, given the DNS inconsistency.

Only other option that springs to mind is to bypass the test for that IP.
So add:

!hosts = 65.54.246.99

to the relevant ACL statement(s).
