Redundant mail path for Exchange 2003
Posted on 2009-07-08
Hi, we have 2 x offices connected via WAN. Each office has its own internet connection (separate to our WAN connection), but all email comes into office 1. The exchange server here then passes emails to the server in office 2.
The internet in office 1 was down all of yesterday, which made me think, is there a way we can redirect our email (ingoing / outgoing) through our office 2 server?
My understanding of it is we can add another SMTP connector to both servers with a higher cost, so exchange will fall back to the secondary connection if it needs to.
We only have 1 server per site, so I'm not sure about this front end / back end / bridgehead arrangement. But I am also curious to know if mail starts coming in through exchange server 2, will it know to automatically send mail up to exchange server 1? (as it has never had to do this before, usually its the other way around)
My thinking may be way out here, hope someone can help out!
