The only real change you'd have to make to the default supplied filter
is to add a check *after* the SpamAssassin call for what you want to 

For example:

# Spam checks if SpamAssassin is installed
if ($Features{"SpamAssassin"})
  if (-s "./INPUTMSG" < 100*1024)
    # Only scan messages smaller than 100kB.  Larger messages
    # are extremely unlikely to be spam, and SpamAssassin is
    # dreadfully slow on very large messages.
    my($hits, $req, $names, $report) = spam_assassin_check();
    if ($hits < 40)
      $score = "*" x int($hits);
      $score = "*" x 40;

    # adding this "if/else" is the only change you should need
    if ($SendmailMacros{'auth_author'})
      # You can put anything you want in the message, of course
      action_notify_administrator("$Sender sent spam with subject $Subject\n");
      # We add a header which looks like this:
      # X-Spam-Score: 6.8 (******) NAME_OF_TEST,NAME_OF_TEST
      # The number of asterisks in parens is the integer part
      # of the spam score clamped to a maximum of 40.
      # MUA filters can easily be written to trigger on a
      # minimum number of asterisks...
      if ($hits >= $req)
        action_change_header("X-Spam-Score", "$hits ($score) $names");
        md_graphdefang_log('spam', $hits, $RelayAddr);

        # If you find the SA report useful, add it, I guess...
        action_add_part($entity, "text/plain", "-suggest",
                        "SpamAssassinReport.txt", "inline");
        # Delete any existing X-Spam-Score header?
