Domain Aliases

This settings page is only available to domain administrators.

A domain alias is bascially an alternate domain name for one that already exists in SmarterMail. For example, if the domain 'example.com' is in SmarterMail and has the user 'user@example.com' added to it, by adding a domain alias for 'example.net', emails sent to 'user@example.net' will be delivered to 'user@example.com'. That means that emails sent to either domain will end up in the same mailbox.

There are a few reasons why a domain alias is used. One is for branding purposes. If you have multiple extensions for an exsiting domain, using a domain alias for each extension means that you won't miss any emails if people send to one of your other domains. It is important to note that you must own each domain you're using in order to create domain aliases. In addition, messages cannot be retrieved with a domain alias email address unless the domain is properly registered at a domain registrar.

To view a list of domain aliases, click the settings icon. Then expand the Domain Settings and Advanced Settings folders and click then select Domain Aliases in the navigation pane.

To create a new domain alias, click New in the content pane toolbar. The domain alias settings will load in the content pane and the following options will be available:

  • Name - The name of the domain alias. The name will be used to create the domain alias email address. For example, if the name of the alias is "example2," the domain alias email address will be user@example2.com.
  • Points To - The domain the alias redirects to.
  • Verify MX record in DNS before add - Select this option to check that the mail exchange record for the domain is pointing to the server. Note: This option is only available to system administrators and prevents users from "hijacking" mail from valid domains. For example if this check were not in place a user could add a domain alias of example.com. Then, any mail sent from the server to "anything@example.com" would go to the domain with the example.com domain alias, rather than to the actual domain.
