First, thanks for replying. It shows the list changes in
action. At least it appears to work as intended. :)

And that'll only work until the next mail service provider
does the same thing (insist mail addressed from them goes
through them). Which, supposedly, they should all be
doing.
Yeah. DMARC isn't the primary reason for bashing Yahoo.
It's more that they have repeatedly blocked all mail from
Fedora domains after a few users signed up for a list,
forgot how to get off it, and marked it as spam. I've never
managed the Fedora domains, but I've managed others and that
sort of thing always left a lasting impression on me.
Likewise, with the converse. Recipient mail service
providers insisting that mail from somewhere must come
through them, regardless of the fact that's not always
practical or possible.
Case in point; many of us have our own domains, and will
use them to the fullest extent (use our domain name, post
through our servers), yet our ISPs interfere (intercept
passing mail, and route it through their own servers).
Are there (m)any ISPs that block the submission port (587)?
I know many block port 25, but if you're running your own
mail server, you really just need to do it from IP space
that you control.
For me, the worst part of having port 25 blocked these days
is that it makes it slightly harder to diagnose issues with
remote mail servers (but only very slightly).
In some ways I don't mind the notion that a mail server
may remove our addresses from the post, preventing spam
from personally reaching us, and stopping private replies.
But it heads towards anonymising the mail, making it
easier for someone to be an ass, or impersonate other
people.
Indeed. It's an interesting balancing act.
