Hello,
I am completing the last phase of a exchange 2007 to 2013 migration, external (and internal) mail is currently routed through our exchange 2007 front NLB cas server.
I have a 2013 sp1 CU10 ip less dag with 3 nodes and all servers running cas/mb roles. We have a external host (vendor) that accepts mail from our external MX records. For smtp redundancy I'm going to:
External > Create another public IP, and route mail to 2 different dag servers from 3rd party gateway (through FW).
Internal > Create 2 dns A records (smtp.domain.com) with 2 different IPs pointing to 2 different host names of my dag servers (round robin). Point all internal apps to smtp.domain.com. My time is limited have not been able to test in lab. Is this a feasible solution?
thanks
