There are a number of models that would likely have far less abuse that 
is true for Internet mail.  As with most deficiencies in any operational 
system, the problem is that it is already operational.  So making 
changes has to overcome the massive rigidity of the installed base.

With respect to Internet mail abuse, there have been many different 
efforts, over the year, trying to impose pre-hoc controls, such as a 
submission cost.  As ideas, they are reasonable.  As practice, they've 
proved to be non-starters.

Consequently, any proposal in this space needs to include a compelling 
analysis of how it will accrue support from existing email users.  Alas, 
so far, no proposal has come close.
