I am in a real bad bind. We are currently moving to a hosted virtual private server for our website, and Google Apps Premier for email from an on-site MS Exchange 2003 server handling both functions.
The problem is that we have redirected the DNS for the domain to the new server, which has broke our exchange email. I had an AName in place for the URL that we use to access our mail (i.e. mail.ourdomain.com - points back to the exchange server IP) - however it's starting to look like that's not going to cut it.
How can I configure my email traffic to flow through our new server toward the old exchange server using DNS settings?
Update: So now I have:
mail.DOMAIN.COM. (A record) 10.10.10.10 (IP Address of Exchange server.) AND DOMAIN.COM (MX record) mail.DOMAIN.com
I don't have a CNAME involved, but this should still route mail through the new server to our onsite Exchange server, correct? As of now, I can log into exchange with https://10.10.10.10/exchange and send mail, but incoming mail is still bouncing. I just want to be sure I'm not having an issue with ports or anything else...
