Keith,

Nicely done. I would add to "Recipient Control Over Whose Messages Are
Accepted" the following points.
- Users want to be able to divulge an email address to a specific party
without running the risk of receiving mail from everyone that party may
choose to share the address with.
- Users want to be able to revoke the right of specific senders after granting
them the rights to send. For example, un-subscribing from a mailing list
should not depend on the mailing list manager honouring the remove request;
it should be a unilateral action on the part of the recipient.
