I have an Exchange 2007 environment.
1 edge server in DMZ
1 mail server
1 CAS server
We use postini to filter incoming spam, I would now like to set up our outbound e-mail to also go through postini. In following their documentation in setting this up reinjection still fails.
It is my understanding that a private relay needs to be in place to allow this action.
What would the best practice be for setting this up? Do I create a new send connector pointing to postini? Do I edit our existing outbound to the internet send connector?
Thank you for any help
