An Alias will allow you to divert any mail that is sent to various address for your domain onto one of your dedicated email hosting accounts.
To setup this follow below steps:-
Login to VIPControl > Email Hosting > Manage > Click on Setting Icon > Manage Aliases page.
You can also setup a catch all function using above steps i.e. catch any email that is sent to an invalid email address for your domain.
A forwarder can be used if you’d like to email another copy of a message sent to your dedicated email hosting account onto another email address. If you wish to set a forwarder for your email account to another email address then this can be achieved by logging into the Atmail > Click on Settings > Mail Options > Enable Forward > Add another email address.
