# Manage Alias Domains

An Alias Domain is an exact copy of a real domain. It is useful when you have multiple domains that should all share the same characteristics.

For example, your company might own several domains: longcompanyname.com, shortcompanyname.com, and oldcompanyname.com, but you don't want to create separate users for each domain. You can set up longcompanyname.com as the **primary domain** and the other two as **Alias Domains**. Every user, alias, or list you set up on the primary domain will be available on the Alias Domains. Remote senders can use any domain name to reach your users, and the message will be delivered only once, into a single mailbox. It's a great way to consolidate your domains.

#### Add an Alias Domain

- Go to the [Admin Panel](https://cp.emailarray.com/admin).
- Log in using your Admin username and password.
- Click on **Domains** in the menu and choose **Alias Domains.**
- Select the primary domain from the drop-down list
- Click on the **New** button.
- Enter the name of the **Alias Domain**
- Click on the **Add** button.
- Make sure to modify your DNS settings and add the MX records for the alias domain. They should be: 
    - Primary with a preference of 5: mx.emailarray.com
    - Secondary with a preference of 10: mx2.emailarray.com

#### Remove an Alias Domain

- Go to the [Admin Panel](https://cp.emailarray.com/admin).
- Log in using your Admin username and password.
- Click on **Domains** in the menu and choose **Alias Domains.**
- Select the primary domain from the drop-down list
- Click on the delete icon next to the domain alias you wish to remove
- An alert pop up will appear, showing the alias domain that will be deleted. Click on **Delete** to confirm.
