Oooh, this sounds promising.  I can't think of a scenario where it would do the Wrong Thing, like send a message to another zone in a non-dire situation.  Also, not relying on a-e to move messages to the other zone means the zone's exchanges don't have to all be in the same cluster/node.

I will definitely try this.

Thanks!
