Something is wrong with the outbound email: the list isn't getting
copies of this:

https://lore.kernel.org/all/yq1v934yysg.fsf@xxxxxxxxxxxxxxxxxxxx/

because you're sending HTML email ... please don't.

I still think setting expecting_cc_ua is the best thing to do because
it's designed for exactly the problem you're seeing, but open coding it
in the loop would be fine as well.
