The alternative requires that a copy of the message still be at the server. 
That works in only some MUA-based models.  Often/typically, the entire message 
is downloaded to the MUA's site and the server no longer has a copy.  Hence, 
it's too late to enjoy merely passing a citation back to the server.

The challenge is the "few days".  It means that the mechanism fails after a few 
days.  Is that acceptable?  Why?
