Since then I have learned that some MTA's will look for an A record if it cannot find an MX record and use the A record instead.
Once upon a time that was near all Micr0$loth did...
Is this acceptable (in a "best case scenario") as a correct method?
It isn't exactly completely RFC compliant, but, it is only a -=Request=-, eh ? But, FWIW, since when is a system =-without-= proper fall backs, a "best case scenario" ?
Obviously some admins I have encountered are starting to host mailservers for sub-domains and domains without MX entries on their DNS zone records. Relying on the A record alone.
Lemmings make a mad dash towards a cliff, every so often, en masse.... * shrug * Go figure. :P
