routing the same domain in / out

Hi there,

Is it possible to route the same domain both inbound and outbound on the same smg device?

Example:

If I have domain abc.com that is considered "local" with the green check mark under protocol, domains (that means I am accepting for abc.com)

Can I then route Email outbound thru the same smg for the same domain for non-local users.

Basically, I am not authoritative for abc.com. I host a few users for abc.com on my exchange systrm. Abc.com is really a router mta with an ldap database where it routes many abc.com Users to many other domains that host other abc.com Users on there Networks.

So basically if I only host 5 abc.com Users locally. Now if someone local on my network wants to send to a non-local abc.com user, I want my exchange (since my local ldap does not contain these users) to route these non-local abc.com Users back thru the same smg device to the internet.

Is this possible?

Thanks.
