In mail from Yahoo Groups (yahoogroups.com) the PRA is the

Most probably Yahoo will not add a Resent-Sender: or

Right. Nor Sender (like Mailman does).

I think most likely MTA admins will disable PRA checking (assuming
they can), because usually it is the users who scream at the their IT
dept saying "how come I can no longer get email from ...". The senders
usually don't find out until later (assuming they *ever* read bounces)
that their messages were not being delivered.
The original sender won't find out ever, as Yahoo Groups sets an
own envelope sender (with no TXT record at all associated btw),
so bounces reach yahoo, and eventually, the participant will probably
be removed from the list for too many bounces.
