This can be done by using the Forward option which is found in the Email Control Panel-> Accounts menu-> Edit Account: in the page which appears you simply need to select the Forward option and specify the destination email address (maximum of 5 email addresses, separated by the ‘,’ symbol).
You can activate a Forward for each email account. By selecting the ‘Enable Save Copy and Alias' option, a copy of the messages will also be saved in the domain account (main recipient).
ATTENTION!!! we recommend that you activate this option only if strictly necessary.
