I'm running a SBS 2011 and and trying to install a SPAM filter on a member server. The configuration requires I use IIS SMTP to relay incoming and outgoing emails through the member server using IIS SMTP.
I have configured the IIS SMTP but don't seem to be able to get it to pass the emails to the SBS 2011.
Is there a way to test the relay between the two servers?
Do I have to do something on the SBS 2011 to accept emails from the member server?
BTW: I am able to receive email on the SBS with no problems.
