A more elegant solution:

server.cf:
        case $key in
        init)   # If you want to log incoming connections, it can be done here
                #echo server "$@" >> /tmp/server
                # turn off filename globbing  <---------------------
                set -f                        <--------------------- add this
                # redefine the log function
                log () {
                }
                ;;


I use this method in my policy based smtp filter without any problems.
