Not really an argument _pro_ adding AAAA-fallback IMHO.
not clear. he might have set up forwarding to user(_at_)domain(_dot_) and it
worked because it just happened that the one MTA doing the forwarding
implemented fallback to AAAA.
I don't think that's much of a pro-fallback argument either, but we
should acknowledge that some existing MTAs do implement fallback.
hmmmm, shouldn't we all acknowledge its the standard to do a fallback
in all MTA (software)? Whether "some" operators (users of MTAs)turn it
off, is another matter.
What I am interesting in finding out, is what is the BCP by the MTA in
fallback situations in the area of retries.
