If I'm understanding you rightly you are arguing against the o=~ or
"relaxed" policy provisions in SSP right?
No. Just trying to understand how senders operate, and how their
policies can affect the effectiveness of DKIM in general and the
security implication of senders' behaviors to DKIM. Adequate security
analysis cannot be done without understanding how users operate.
I do think signers need to be made aware of the risks of using
relaxed policies.
During transition, relaxed policies will definitely be needed, but
if DKIM becomes the norm, relaxed policies will hopefully go away.
