Details about Alias Domains

Alias domains automatically inherit the email configuration of their primary domain so that emails addressed to a recipient at the alias domain are delivered to the same recipient in the primary domain. 

The advantage of alias domains is that they require no ongoing configuration once set-up – everything works automatically. 

You should read the following notes carefully before deciding whether alias domains are appropriate for you: 

    • Alias domains are not configurable. You can’t, for instance, alter their spam configuration or change the destination delivery – they simply inherit the settings of the primary domain.

 

    • Emails addressed to alias domain are delivered to the primary domain – e.g. if test.co.uk is the primary, and test.com is the alias, then emails addressed to bob@test.com will be delivered to the destination server as bob@test.co.uk. This can cause issues if the customer server is performing routing based on the domain used.

 

  • You can’t have differences between the domains – e.g. you can’t have sales@test.co.uk delivered differently to sales@test.com.
