I'd doubt it. There is no requirement in any of the RFC's that an MX records
exists. If there is no MX, then an MTA will send to the first A record it
finds, preferably the domain itself.

Having said that, I know more in about mail and DNS in general than I do
about Exim in particular, so am quite ready to be told otherwise.
