DKIM author domain signing provides strong authentication where it
matters, which is where the domain owner cares. For well-known
addresses it's merely a matter of putting them on a separate domain or
sub-domain from user accounts. 

If a university server accepts spoofed submissions then they clearly
don't care that one user can spoof another.
