I am needing to configure our Front End Exchange server to forward all outgoing mail to a 3rd party filtering solution.
Our current setup is:
4 back end server
1 front end
All outgoing mail is sent to the front end via SMTP connector with front end listed as the local bridgehead.
In order to use the 3rd party as a smart host, where do I enter their mail server info? There are two different places I can see to enter the smart host:
A. in the existing smtp connector -- "Forwar all mail through this connector to the following smar host"
B. under the front end server, Default SMTP Virtual Server there is an Advanced options under Delivery to enter a smart host.
If Option A is used, how does this affect the back end servers routing internal mail to each other?
