How do I configure the ESA to route incoming email to my corporate email servers?

In order for your ESA to deliver email to your corporate email servers, you must configure the ESA to use
that host as a destination for delivery. This can be done by using the 

smtproutes

  command from the

Command Line Interface (CLI). 

The 

smtproutes

  command allows you to redirect all email for a particular domain to a different mail

exchange (MX) host.

mail3.example.com> smtproutes

There are no routes configured.

Choose the operation you want to perform:

− NEW − Create a new route.

− IMPORT − Import new routes from a file.

[]> new

Enter the hostname for which you want to set up a permanent

route.

Partial hostnames such as ".example.com" are allowed.

Use "ALL" for the default route.

[]> example.com

Enter the destination hosts, separated by commas, which you

want mail for

domain.com to be delivered.

Enter /dev/null by itself if you wish to discard the mail.
