In my installations, I have VPN's between some sites.

To maintain encrypted transfer of messages between offices, I use the
following router:

VPN_router:
driver = manualroute
transport = remote_smtp
route_list = host.com 192.168.1.51 byname

This way, anything sent to *@host.com will go across the VPN instead of out
over the public network.

Now my problem. Our VPN hardware went down and email wasn't delivered. It
took over 24 hours before anyone called me and let me know, and of course it
was an emergency by then. I discovered I needed a fall-back configuration
in case this happens again.

Can you define multiple IP addresses in the route_list option of the router
so that if the standard address (192.168.1.51) is not available it will use
the secondard and go ahead and deliver it?

(IE: route_list = host.com {192.168.1.51 OR 123.45.67.87} byname)

Thank You
