Truism. That is an entirely different statement than saying (as you did
in your original post) that having an MX record is a de facto requirement
for sending mail. Domains lacking SPF or DKIM/DomainKeys setup will find
themselves having trouble sending to mailboxes at Yahoo and Hotmail, so
is that a "requirement"? No.
