We use GoDaddy for hosting
We use Google Business Apps for email (primary) - mail.ourdomain.net
We are an electric utility and need to send over 3000 bill notifications once a month.
I used to have an internal mail server before we moved to Google Apps. It is still alive and I have the bill notification server pointed to our internal mail server. But many do not get the emails and I highly suspect due to no mx records validating the email notifications from this server.
I assume (correct me if I'm wrong) that I need to update records on GoDaddy to indicate it is a valid domain's mail server.
We want it to be mail2.ourdomain.net
How do I do this without affecting our primary Google mail?
