If it works 100% of the time for you, what can I say.

I doubt I'm an expert. Current versions of Postfix and sendmail
handle the CNAME. There are some configuration cases where sendmail
may generate a delivery failure. I don't use major email hosted
providers as a yardstick. There was one major email hosted provider
that rejected messages if the sending domain listed an IPv6 host as
one of the MX targets.
I suggest that we agree to disagree as we are not arguing about the same thing.
