Testing New Smarthost - IRONPORT

We recently purchased IRONPORT (ESA) Email Security Appliance for our organization.
We currently are running Tumbleweed Mailgate as our Security & SPAM filter.
How can I test IRONPORT without taking Tumbleweed Mailgate down?

We are running Exchnage 2010.  Is there a way for Exchange 2010 just to use IRONPORT without taking down Tumbleweed Mailgate?  We just want to test the IRONPORT to see if the SPAM Settings and mail flow is correctly configured.

Is there a way to route emails to IRONPORT?

Well first you need to setup you MX records to point to the Ironport.

Let us assume you domain is domain.com and you have 1 MX records. So when you type the following command from Windows you would get something like this:

nslookup -type=mx domain.com

MX    10 mx1.domain.com

We are assuming mx1.domain.com is pointing to the IP address of Tumbleweed Mailgate which is accessing from the Internet.

Now you would need to change the MX records to point to the Ironport also to make a little change and set them you like this so that mail should go first to Ironport and it Ironport is not reachable or down mail would try to go to Tumbleweed Mailgate. After making the changes it should look like this:

nslookup -type=mx domain.com
MX    5 mx0.domain.com
MX    10 mx1.domain.com

Assuming mx0.domain.com' s IP address is pointing to Ironport which is accessible from Internet, but make sure only port 25 is opened, rest all should be closed.

After changing the MX record I would give a cost of 5 to IRONPORT and a cost of 10 to Tumbleweed?
