Reserved Domain Names

System administrators can prevent certain domains names from being added to SmarterMail. For example, domains that are already used for free email services, like or, are ideal additions to the reserve list as allowing administrators to add such domains to SmarterMail could affect message delivery. Similarly, domains that are traditionally reserved for testing and documentation, such as or are also ideal candidates for the reserve list.

To view a list of reserved domains, click the Security icon. Then click on Advanced Settings and Reserved Domain Names. A list of reserved domains will load in the Reserved Domain Names view.

In general, the following actions can be taken:

  • New - Adds a new Reserved Domain Name entry.
  • Edit - Click on the card entry to modify the domain name.
  • Delete - To Delete an existing entry, click on the caret (∨) shown in the upper right corner of the card and click Delete. To delete multiple entries at once, click on the Select button to open the multi-select tool.
