Agreed: that is how we designed submission mode to be used. At Cambridge
we allow our users to use any email address with our email system
(especially role addresses, but also vanity addresses, hem hem) and
submission mode marks the message with their authenticated identity,
complete with their full name. However you won't get a proper view of it
from this message because the list smashes the Sender: header...
