My department has an internal SMTP relay running on a Windows 2008 R2 using IIS 6 and was configured to use an external smart host and that was working fine.
Recently our IT department set up their own internal SMTP relay and wants us to utilize their SMTP server and shut down the 3rd party smart host (guessing to save money)
We have a ton of jobs and notifications that are all pointing to our existing SMTP server and I don't want to have to try and track them all down and update to the new one.
Is there a way to configure our existing SMTP to relay to the new SMTP server which will then deliver the email?
(99% of the emails are internal only and I know the one application that is sending external and I can reconfigure that manually, so this will all be internal email routing.)
