Exchange 2007, SP1 RU8
We have 2 Physical boxes with CAS & HUB roles on them.
I have a specific requirement from business:
One of their application is being hosted by a vendor on an external network.
This application sends out mail notification to us using the vendor hosted SMTP services.
Now what the team want is that the externally hosted application should use our corporate SMTP Services to relay that application mails.
I belive thsi is omething that can be done by having a secure SMTP server.
I am not sure on how to set that up.
We also have ISA 2006 server publishing exchange services.
