Actually, if I understand correctly your postal analogy would be more like
you wouldn't be able to use public mail boxes, but no matter where you
are, you should be able to drop a letter in your mail box at home where it
will be picked up by your own mailman.  Of course, the ability to drop a
letter directly in your own outgoing mail box is another issue not directly
related to SPF.  It's a matter of allowing your mail server to relay mail
for
users who can authenticate themselves.

So back to the postal analogy,  you'd could drop a letter in your own
mailbox from anywhere in the world as long as you had the key.
Although, if the authentication is done by password sent in clear text, I
don't think I would like that option.
