1 and 3 are out of scope for this group's work. For 2, DMARC, and tweaks to
SPF and DKIM to support DMARC, and this group's focus. Right now, we're
working on a standards track version of DMARC.

To your notes about sender authentication needing to become mandatory, do
you have any recommendations on items that make this difficult for senders
that should be addressed as part of the DMARCbis process? We had a call for
these items that closed on 5/24, but welcome other feedback.
