Block the outside world from reaching anything but the filter by firewall or other means. Otherwise the spammers will find it and go around your filter.I have a virus and spam filter device that can do VRFY commands to reject invalid email before it gets to the next mail hop. How can I configure the SMTP server to only allow VRFY commands from one particular IP address, and nowhere else? I don't want spammers to be able to hammer on the gateway looking for valid addresses to send to.
