I just did an upgrade from Exchange 2003 to 2010. I have the Hub transporter setup with one external DNS going thru Google/Postini to filter any spam, viruses, etc. Everything is working, except our Sharepoint 2007 library addresses.
I have added the Sharepoint IP addresses to an Internal Receive Connector with TLS, Exchange Server, & Integrated Windows authentication boxes checked. All Permission Group boxes are checked except Partners.
The emails are being sent, but they are going to Postini and being returned with the following error:
Postini gave this error:
Host not found for domain:mcc-moss.company.com - psmtp
Our Sharepoint server is setup with an internal DNS MX record on domain name mcc-moss.company.com. Our main domain name is company.com.
I don't need Sharepoint email going thru Postini, so what do I need to do to have mcc-moss.company.com deliver directly to our Exchange server (MCC-EXCH) for delivery?
Here is info on an email sent the other day:
