How to create a new email address:
Select the Email Accounts link in your Email Management row. Type the new address in the Add New Address field.
Select the domain name to which the address will be attached and click add.
To create your email address as a fully-functional email address choose the first option. Choose the second option if you would like all mail sent to this address to be forwarded to an existing email address. Choose the third option if you would like the email address to fully function, but you would like all messages to forward to an existing email address. Check the optional box if the email address should automatically reply to all incoming emails with a message you define. Click continue.
Enter a password of your choice, or click the option to generate a random password. Click finish.
