is rumored to have said:
Nearly 1/2 a century later, it's still the case that most mail clients
will look for
address RRs in the absence of an MX.
Because failing to do so would be ignoring a requirement of the SMTP
specification.
Any SMTP client which does not fall back to the A record when no MX
records exists is fundamentally broken.
