The issue is worse that that..  It will cause the list email to bounce
to all the recipients of the list.  As a result, Mailman will happily
unsubscribe everyone from the list once some yahoo users send mail
there.

On the lists I maintain I just turned off automatic bounce processing.
It just means that yahoo-using users wont get their email seen by list
members that have DMARC processing turned on.
