Over on my side, the receiving end of these emails, there is my
spamassassin. SA discovers the DKIM signature and is able to validate
this signature against the Yahoo server which is totally undesirable
in my opinion.

SPF requires the mail to be sent out through designated hosts. A DKIM
pass for the correct domain means that the email passed through a host
with access to the signing key. DKIM provides better authorization than
SPF.

RW is correct. This email did not go through a Google mail server. Looks
like the sender is using a mail client to send through Yahoo with the
intention to get someone to reply back to a gmail.com address.
Does anyone think it would be beneficial to extend the FreeMail plugin
to detect these headers having different sender and reply-to FREEMAIL
domains?
what does Sender: header give us in addition to envelope from?
this mail already hit FREEMAIL_REPLYTO
