In the system I describe, the email address *is* "a unique string
issued by the receiver to each potent[u]ial sender."  This has the
charming property of working very well with the existing e-mail
system and without having to have each correspondent manage a directory
of "key" words for each person they want to correspond with, updates to
that directory, etc.

No system does.  The point is to be able to tell who leaked/abused/etc
it, and more importantly, to be able to trivially terminate the sender's
ability to use the address, making that entry on their list completely
useless, or better yet, annoying them by clogging up their mail server,
if you do sufficiently BOFHish things.
