I just wondering how to get emails that are sent to one address to forwarded to be forwarded to multiple address.
Go to your control panel and select mail > Manage addresses.
Here you can create a new address or edit an old one. While creating or editing you will find a box to list multiple addresses.
Also be sure to untick “deliver to this mailbox:”
Delivering to a mailbox and to other addresses in one step hasn’t worked for me in the past.
Create the mailboxes first that the mail will be delivered too, then create a new address, enter the email addresses into the box provided to forward emails too.
