Please read section 5 of rfc 2821.
"If no MX records are found, but an A RR is found, the A RR is
treated as if it was associated with an implicit MX RR, with a
preference of 0, pointing to that host."
Thus Paul's setup not only works, it _should_ work as it is compliant.
Any MTA which cannot deliver mail to Paul's system due to the lack of
an MX record is broken.
