We have just built an MS Exchange 2012 R2 server and need to configure the "Mail Flow"/connectors properly to send outbound emails to 2 IronPort devices and allow inbound email from those 2 devices.
I am able to telnet from the Exchange Server to both Ironports using Port 25 but see no connections from Exchange itself (no outgoing emails ever arrive at the IronPort).
Telnet from IronPorts to Exchange gets a 4.3.2 message that the Service is Unavailable. Messages are queued on the IronPort but not delivered to the Exchange Server.
Does anyone have working examples of how to configure the connectors on Exchange to do this? PS. It worked with Exchange 2003 :(
In my example Exchange -> Ironport is 192.168.4.15->192.168.4.175
IronPort -> Exchange is 192.168.24.175 -> 192.168.4.15
