I have a problem. I am trying to set up redundant routes for mail flow to and from Spain to our head office in the UK. Here at head office we have two clustered 6.5.3 servers and in Spain there is a 6.5.1 box. We've set up connection documents at each end sending mail to/from one of the cluster boxes with a routeing cost of 1 and to the other with a cost of 2. The theory is that the connection to the cost 1 server and Spain is via a high speed VPN tunnel and the other is via the existing, heavily loaded WAN. If/when the VPN tunnel drops or dies for whatever reason the mail should switch over to the WAN link. It is essential that mail flows constantly.
This works perfectly in Spain; mail waiting to transfer automatically goes to the other box. Here, I was hoping that queued mail would reroute via the secondary server but instead it just piles up.
Has anybody got any ideas?
