No. There is no such requirement in the RFC's not even a hint.

Bluetie.com has made very some erroneous assumptions about how to check
for legitimate mail servers. Bluetie.com would refuse e-mail from all of
the public schools in the State of Arkanas based upon their policies.
And I do mean all because I'm hostmaster for the TLD.  

The vendor should tell bluetie.com to "fixit".
