My concern has to do with whether the SSP of the other From (author)
domains has to be considered as well. Just as the point has been made
that it's not proper to handle this case by arbitrarily picking the
first From domain, I believe that it's also not proper to use Sender for
this purpose. Given that belief, the question of whether Sender is
signed or not is moot.

In the case of multiple from: addresses, wouldn't promoting (maybe
this is the wrong word) the from address(es) of the signing domain to
author resolve this?
