Adding a Domain Alias

A domain alias allows different domain names to direct to a single domain address. For example, your domain is domain.com, but you want users to have an address of example.com, you can create example.com as the alias for the domain.com address. Sending mail to user@example.com is the same as sending mail to user@domain.com.

Note:

A domain alias is a domain name just like your primary domain name. You must own the domain name and verify your ownership before you can add it as an alias.

You can create a domain alias from the administration console Domain tool bar>Add a Domain Alias link. The domain alias is listed in the administration console Navigation pane under Domains.
