Add domain alias to Zimbra

If you have multiple domains that you want to use on Zimbra, but want to use the same mailboxes than Domain Aliases are your answer.  To setup a domain alias, do the following:

1. In the client area, go to Services -> My Services and click on the Zimbra service
   1. NOTE: If you have multiple Zimbra services, pick the plan that you want to add to
2. Click "Domain aliases"
3. Enter the domain in to the New Domain Alias form
4. Pick which domain to alias
5. Submit the form

You should be set at this point.

NOTE: If you do not see Domain aliases, your Zimbra plan may not offer this and an upgrade would be needed.
