Subject: [dmarc-discuss] Yahoo! DKIM Signing Practices Produce Fragile
Signatures
With obvious implications for DMARC failures. See the postfix-users thread
that starts here:
http://archives.neohapsis.com/archives/postfix/2014-10/0138.html
It would be helpful if Yahoo! were to dial this back a bit and stick with the
recommended fields to sign (i.e. drop Received and Content-Length). Signing
those fields inevitably makes the signatures more fragile.
