But you will need a routing daemon running to use it. Another possibility would be to have a script run every 5 minutes in cron that pings the first gateway, and if the ping fails, change the route. It would also need logic to fix the first route when the primary gateway starts answering pings again. -- MailScanner is like deodorant...
