Smart Mail allows email administrators to create a limited number of email aliases to their selected plan.
An email alias, sometimes called an email redirect is a record in a mail server which redirects a nominated email address to another email address hosted on the server.
No emails are stored in the alias account, however the alias address must be supported by the correct DNS.
The domain to which the alias belongs must have its MX records pointed to our mailservers for the alias to work.
