I have a client running SBS2008 who share their domain with external email recipients. Their domain is customer.com, email is hosted on a 3rd party mail server, and their exchange server grabs mail via POP3 connector. They also have many external users with customer.com email addresses.
Previously they had SBS203 which hasa neat option to send email for unresovled local recipients via the smarthost and out to the internet. This worked fine for emailing external recipients from inside the network.
In SBS2008 the process is different, requiring you to change the accepted domain type to internal relay and add an additional send connector for the shared address space (customer.com).
I followed the instructions here to the letter:
also same thing is stated here:
however email to external customer.com addresses still bounces with an NDR from the exchange server saying no recipient found.
What am i missing? do i need to change the Cost on the default "Windows SBS Internet Send SBS" send connector or my custom connector?
Do i need to restart particular services to make the change effective?
