Nope, the exception would go for a whole mailing list, not for every of
its users. Anyway given that this would be optional plugin for sa, it
would be only used by people / organizations who care about authenticity
of the message sender and these that would be OK with the fact that mail
addresses within this domain just couldn't be easily used for stuff like
mailing lists. Believe me, there are people or organizations who would
happily exchange ability to use mailing lists within some domain for
guarantee that their emails can't be spoofed in no way (at least within
their own domain).

On the other hand, SA is a points-based system. If you checked SPF

the score at 0.001 and monitored the non-spam hits for a while, you
could probably come up with a pretty good list of exceptions before
upping the score. (Of course this assumes you are in a position
where you can legally look at the messages passing through your system.)
It could be helpful, or there could be too many exceptions to be
useful. I'd say it's worth a try to see what happens.
I can immediately guess this rule would need way too many exceptions
to be
useful. And when anyone in the world subscribed to any list, it would
need
an exception.
