Email aliases allow you to create email pointers or email redirects. In simple terms an email alias is simply a forwarding email address to another email address.
Firstly, log into hostControl and select "Email Accounts" from the menu, underneath the "General" section.
Select your domain name from the drop down list and then select the "Email Aliases" tab
Select the "Add Email Alias" button
Enter the email prefix name for the Email Alias, then enter the destination address for it and select the "Create Alias" button
You should now see your newly created Email Alias in the list
In the above example, any emails sent to firstname.lastname@example.org will now be forwarded onto email@example.com.
