FWIW we've been rejecting posts coming from addresses for a
long time now, since DMARC was first introduced.  We didn't get around
to blocking other domains owned by Yahoo such as or national
yahoo subdomains, but I assume (without checking) that those will cause
trouble too and we will have to block them out in order not to fill our
queues with useless bounces.
