Oh yes. There are lots of one-box sites that don't seem to both with MX.
Personally, I wish the rules would change, because MTAs waste a lot of
retries sending to bad domains that have A records but no MX. Often
happens if a PC user mis-configures an MUA, for example.
We insist on MX records within our local domain, and use
mx_domains = *.cam.ac.uk
on our MTAs. That at least gets rid of the problem locally.
