We changed the DNS settings on the firewall, and exim seems to have
recovered nicely.
We aren't (currently) using blacklists (DNS-based or otherwise) on this
system, But I may switch to a caching DNS setup if the problem recurs.
Thanks for the suggestions.
It's nice to know it was not the part of the system I'm responsible for.

I highly recommend this, especially if you use DNS-based blacklists.
It's easy to do; in fact many Linux distributions have an out-of-the-box
configuration for it.
