Hello All,
I am trying to set up my mail environment for redundancy including dual ISP's.
Currently using Exchange 2007 and moving to 2013 DAGS.
I have Barracuda spam filters in my 2 DMZ's
I am OK with Multiple MX Records.
I hope to not have any single point of failure.
Where I am having a problem is the Gateways on the exchange servers.
Can the servers be set up to use whatever gateway the smtp request came in from?
