Exchange 2010 Send Connector with narrow address space not being used

Last Modified: 2012-08-20
Dear Experts

We have an Exchange 2010 infrastructure with a single SMTP Send Connector, address space is * with a cost of 10.
I created a new Send Connector with a more narrow address space of <domain1.com> with cost of 1. This connector will route e-mails through a new smart host. I am performing some tests on a new IronPort appliance.

I am unable to get any e-mails (from for example test1@domain1.com) to be routed over this Send Connector. All e-mails are still being sent out through the default Send Connector.

If I send an e-mail from for example Gmail to test1@domain1.com, they are routed in through the new IronPort gateway.

I have also tested with telnet to port 25 from my Exchange HUB server to the new IronPort and it works.

What am I missing?

Appreciate your help.
