The default settings on the SMTP filter are pretty thorough. In my own experience changing these commands can have an adverse effect on incoming mail traffic as a whole Good or bad. I would tend to lean towards letting mail security software handle the messaging and would highly recommend GFI Mailsecurity for this task. <br />
