Exchange 2012 R2 Email Flow to/from IronPort C170

Answered Question

Hi,

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

 

Thanks!

Definitely a good answer and very helpful information!

 

We had an Exchange Expert stop by today and check out the setup. It turns out I had way overcomplicated things. I'll document them tomorrow and update this post.

For the "Recieve Connectors" we reset everything to the default and made sure "Scoping" for all was open to 0.0.0.0-255.255.255.255

For the "Send Connectors" we made a new connector called "IronPort" with the following properties:

Delivery: Added 2 smart hosts 192.168.4.175 and 192.168.4.176 - which are the Data1 NIC on both IronPorts and have the hostnames OutboundEmail.myco.com and OutboundEmail2.myco.com

So, Simplifying was the way to go.
