Excellent, I'm glad we found some common ground. :)

If you'll pardon me saying so, it seems that you have a pretty
well-defined agenda through which you're viewing your "facts." But
again, I won't quibble.

Actually it's squeaky clean, and my IHP has no tolerance for
shenanigans. I chose them partly on that basis.

I didn't say "universally true." I chose my words in my previous message
carefully, and I stand by them.
However what IS universally true is that the holy triumvirate of
rDNS/SPF/DKIM will only make it more likely that your mail will be
accepted, and is the only way to avoid outright delivery failures and/or
arriving in the spam folder for many receivers, and the value of "many"
Given that we seem to be in agreement on that, hopefully we can now all
move on. :)
