iRedAdmin-Pro: Priority of spam policy used in iRedMail & iRedAdmin-Pro

With @lookup_sql_dsn = enabled in Amavisd config file, Amavisd will lookup spam policies from SQL database amavisd for different accounts. The priorities of different spam policies are:

  1. Highest: per-user spam policy set in user profile page
  2. Lower: per-domain spam policy set in domain profile page
  3. Even lower: global spam policy set in iRedAdmin-Pro: "System -> Anti Spam -> Global Spam Policy"
  4. Lowest: server wide spam policy defined in Amavisd config file.
