Ah, I do know of this.  It's called the DRAC standard (dynamic remote
authentication control ???).  Anyway, no it's not implemented yet, but was
planned as an eventual feature to add.  Like you said, the POP3 server needs
to get the remote IP address and add it to some list of valid addresses that
last for a while.  Then the SMTP server can flag incoming messages are valid
or not based on that.

It's a bit tougher because James allows for delayed processing, so we'd have
to figure a good way to flag a message as from a valid dynamic IP address.
Hmm... that will take a bit of thought.  Other than that, like you say, it's
not very difficult.
