Yahoo problems again

I'm running a CPanel version of mailman. I've been seeing a lot of the following errors of mostly yahoo.com users but a few other providers as well.

followed by a forwarded message that had been sent to the list by another user. -which I don't know how to deal with. And also, I just had a yahoo user try to send something to the list and he was completely blocked:

I'm in search of old snowplow blades, parts, frames, pumps etc. to rebuild.
This would be for a truck or jeep. I'm not interested in ATV plows.=20
Please reply if you have anything for me to look at.=20
Thanks, Tim

This is a Yahoo glitch. They are reporting a bogus reason for a list message to a Yahoo address that doesn't exist. See <https://forums.yahoo.net/t5/Delivery-errors-5xx-and-421/554-delivery-error-d...>
And also, I just had a yahoo user try to send something to the list and he was completely blocked:

It appears that spam detection software on your list's server is rejecting this message as spam.
