This is the setup:
I have registered a domain (XXX.COM) on Google App, through enom, where by browsing to gmail, users can easily access their mail.
I would like to bring an Organisational Exchange Server to the party!
I have gone for the whole-brain approach, and internally registered a domain (XXX.DOM).
The Exchange server is behind a router, therefore registered with a private ip (192.168.X.X). It however, can still access the internet via NAT configuration on the router.
Internal mails, where users are registered as user@XXX.DOM work fine.
So this is my dilemma:
1. Is there a way for new users being created to AUTOMATICALLY have their email addresses registered as user@XXX.COM
2. (the tricky part) Link Exchange to Google.
NB: I have obtained the MX records from Google and added them to my DNS server.
(I KNOW ITS QUITE A BIT BUT EVEN A TUTORIAL LINK WOULD SUFFICE)
