Yes! And that's in fact what one would expect.
They can't be expected to distinguish between a well-meaning
mail-forwarder and a spammer forging Received headers.
To avoid getting blacklisted, improve your filters for the forwarded
mailboxes, or tell your Yahoo users that you will no longer forward
their mail to Yahoo. At the very least such users need to be taught
to not report to Yahoo mail you forward for them as spam.
