What Mark was saying is that you need to set REMOVE_DKIM_HEADERS=Yes
(current release), or utilize CleanseDKIM.py, to purge incoming emails
of pre-existing DKIM headers.   Secondly, you then need to sign your
outgoing emails using your own DKIM keys.   You can NOT receive DKIM
signed emails, append Mailman headers, and reflect those emails on to
any host (Yahoo! or otherwise) that does DKIM checks.  Mailman's
header modifications invalidate pre-existing DKIM keys.
