Let's say we've an organization named Test, with a domain test.org. The test.org domain is currently registered through Go Daddy but the DNS is not through Go Daddy, its handled by another vendor. I plan to switch the DNS to Go Daddy, but how can I do this so that email will be routed without their being any email downtime? In Go Daddy, once I set the DNS to be handled in Go Daddy, I can't set all the MX and A records until the DNS change takes effect, which seems like that would create a few hours(?) in which email won't be delivered. Thanks for your help.
