That said, some systems, such as our own, have a one attempt only for the "Implicit MX" rule. i.e. No MX -> A Lookup --> 1 attempt only.

This past week alone we would have electronic mail communications fails with legit customers lacking MX records if this rule was enforced.

I just can't see this happening. I will have to see snow balls falls from these South Florida skies before I would have our SMTP system changed.

The concept is to first deprecate use of A records for discovering inbound SMTP servers. After some period of time, then obsolete the use of A records for this purpose.

Well Doug, go ahead and proposed it, write an I-D, see how it flies in IETF-SMTP. And while you are there see if you get the IMC.ORG to stop using MAIL.IMG.ORG as the return path domain WITHOUT a MX record.

Using your concept, you effectly stopped all bounce mail back to their return path.
