J. K. is setting up his postfix to relay mail via his ISP.  This isn't
much different a setup than a Mutt user would have or a Windows user
might have where their antivirus software installs itself as an
intermediary between the mail client and the real SMTP server.  His
mail should go out via his ISP, pretty much like it would if he sent
it directly via a client like Thunderbird.  How's that "direct-to-mx
from a dynamic IPA"?

If everything seems to be going well, you have obviously overlooked
something.
