    In my file I have now :
    #sub spam_scan ($) { 0 }
    sub spam_scan ($) {

    instead of what you have shown above ...

    If you have done an apt-get install amavis-postfix, I think it should
    have installed Razor.

    apt-cache show razor
    Description: spam-catcher using a collaborative filtering network
      Vipul's Razor is a distributed, collaborative, spam detection and
      filtering network. Razor establishes a distributed and constantly updating
      catalogue of spam in propagation. This catalogue is used by clients to
      filter out known spam. On receiving a spam, a Razor Reporting Agent (run
      by an end-user or a troll box) calculates and submits a 20-character
    unique
      identification of the spam (a SHA Digest) to its closest Razor
      Catalogue Server. The Catalogue Server echos this signature to other
      trusted servers after storing it in its database. Prior to manual
      processing or transport-level reception, Razor Filtering Agents (end-users
      and MTAs) check their incoming mail against a Catalogue Server and filter
      out or deny transport in case of a signature match. Catalogued spam, once
      identified and reported by a Reporting Agent, can be blocked out by the
      rest of the Filtering Agents on the network.
