ALL senders, not an option by sender.

Mailman does not know that I do, or do not have spf on rellim.com.

And would be very weird if mailmman keeps bouncing around between
modes.  That would make phishing easier.

It IS necessary.  Sometimes 50% of devel@ email is bouncing.  Many
users keep getting punted from the list due to excessive rejects.

Yup.  Yahoo and gmail, the big ones.  Can't fight tham.

So, is it better or worse now with your megapath?

"nobody"?  How about I add you as a list admin and you can see how
many nobodies we have?  Fully 50% of my posts, with SPF, were getting
bounced some days.  I had DMARC reports to prove it.

So maybe this particular setting is not optimal, but something had to
change, the situation was bad.  I'm willing to try other mailman
setting.
