  It can be argued that e-mail spam made most self-hosted e-mail unusable.

    That argument is not compelling, given the number of people and organizations that self-host email.

      The problem is not that it's difficult to run an SMTP server - botnets run millions of them. The problem is that telling a legitimate one from one that sends spam is an arms race.
