  It's happening today.

  People with lots of money to spend on machines don't necessarily
know how to administer them.  As a result, their machines "attack"
people with less money to spend on machines.  There have been cases
where an "owned" machine was sending 10^6 messages/day to one
destination, and the administator of that machine hadn't even
noticed...

  Similarly, see a number of virus outbreaks where large numbers of
SMTP clients overwhelm other peoples mail servers.  If the viruses
were forced to go through the ISP's MTA, then that MTA might go down
under the load, and therefore protect everyone else.

  It happens.

  I don't think quotas would help, or be politically acceptable.  If
SMTP had something like TCP's slow-start, that would be a better
approach.
