The ideas presented here http://cr.yp.to/im2000.html
address many of the concerns of SPAM/SPIM

The main point is moving responsibility (and COST) of delivering a
message from the reciever (as it is now) to the sender. It's sender's
interest to take care of delivery.
This way we don't need any artificial "challenges" (images,
cpu-intensive tasks) on the reciever side. Keeping the message
available is costly enough.
There is no way of filling up of reciever's mailbox.
If the sender wants to send one million od messages, it's HIS job (and
cost) of keeping them. One cannot distribute the cost to one million
