Now several things can happen in the state graph.
a. Sender has no more msgs to devlier anyway.
b. Sender has more, and follows Recip's desired 1/h
- At some point, Recip decides that Sender has been faithful,
and may be allowed a higher rate.
c. Sender has more, and ignores Recip's desired 1/h
- Sender is blacklisted.
Optionally:
d. Sender has more, and requests a higher rate allowance by providing
an accreditation, hashcash, 'introduction protocol' referral ID,
etc.
e. Sender provides a one-time, or reusable key that was provided out of
band by recipient - i.e. when signing up for a mailing list -
which entitles Sender to a higher rate limit.
f. Sender pretends to be 300 other people and sends you buckets of spam.
Bad guys won't play by your rules.
