We aren't able to do that because for many years we have supported roaming
users by recommending that they use their ISP's email servers to send
email using their @cam email addresses. Of course we now support secure
authenticated submission from anywhere, but we still have nearly 10,000
users with insecure settings...

This is an area where general policies can make a significant difference
to what is technically feasible.
