Your plan assumes at least two things:
        (a) that spoofers don't have access to privileged accounts on *any*
machine that might send mail, and
        (b) that people maintaining SMTP/TCP mailers would eventually change
their SMTP senders to send from ``privileged'' ports.
Neither of these is particularly true. But most compromising is the effect
you'd get if (b) were true, the convention became widespread, and yet (a) were
false: all random spoofers would need is to be a sysadmin on some dinky
workstation, and all the ``protection'' you thought you had would vanish.
