I think this will always forward messages to the first entry, and so it will not do what you want. We've had the same request and so we've defined all our store&forward IP's in a simple database table. This database contains domains, primary and eventualy secondary MX IP's. Then we've set up our monitoring system to try to reach the primary MX on port 25. if this will fail two consecutive times the action is a simple script that does the following 1.) mark this domain in the table as fault 2.) read all active entries from the table and choose the primary MX or the secondary if marked as fault 3.) write a new hosts file 4.) stop and start the Imail smtp service If the monitoring system can see again the primary MX on port 25 there is a similar script that put's back to the primary mx this domain.
