I think I have figured it out.

   * The above settings are correct
   * You will see a virus scan in the email header
   * You will not see a spam scan in the email header
   * Mail is actually scanned by SpamAssassin

I had to do some reading of the config files in /etc/amavis/conf.d.
There are spam settings in 20-debian-defaults. By default Amavisd-new
doesn't add any spam header info on anything below a score of 2.0. I
changed the default to 0.0 and I get spam header info for every email. Nice!

These settings bring up a few questions.

   * SpamAssassin can have user defined settings. How does this work if
     Amavisd-New has its own settings?
   * How do I set a global default SpamAssassin setting?
         o I'm guessing there isn't one if Amavisd-New is controlling
           these settings.
