I think VERP is just a generic name for rewriting the envelope sender for
each message. DJB's document describes using this to identify which member
of a mailing list a bounce belongs to, or which individual message out of a
set was bounced. He doesn't consider envelope forgery.
He does in ezmlm list manager ( http://cr.yp.to/ezmlm.html) to handle
subscriptions reliably. Here is a return address to be used to confirm
your subscription intent

Looks familiar...
SRS proposes to implement the subscription handling part of ezmlm for
every email user, but to handle (back) forwarding of bounces, some
people suggest that some subprograms (like qmail-local) of existing
MTAs would have to run setuid.
