Right.  Standard for a "modern" consumer-grade ISP in the U.S.

Yes.  The boa.org domain infrastructure and maintenance is
self-serve and all-volunteer.  (Thanks, Russ!)

How would a domain-package smarthost help, if I couldn't get to
its port 25 because of the ISP firewall?

Of course I don't know the individual situations of others who have
posted this question and its answer to various on-line forums.
But it's common enough that it was easy to find the answer and
patch my Debian exim4 setup to get the desired results.

You can see the DKIM my exim4 added, before passing to an ISP smarthost,
if you look at the headers of this email.
