That's the part I don't understand.  Mail from my list will not have
a yahoo.com envelope sender.  And if I remove the DKIM header, what basis
could third parties possibly have for considering the email to be forged?

Anyway, for now, I'm simply going to ban yahoo.com users from posting
to our mailing lists until I sort this out.
