I have 4 email accounts and out of those 4, 3 are hosted at my own server and 1 is hosted at Microsoft Exchange Online. What I would like to do is that I would like to deliver emails for those 3 email accounts which are hosted on my server locally and emails for that 1 email account to be forwarded to Microsoft Online Exchange. I was previously using Google Apps for split-delivery and it was working fine but my membership expired. I am running WHM and cPanel on a VPS running CentOS 6.
Add an alias for the address that should be delivered to the Exchange server with the domain of that server. This would go in
