As soon as you confirm your new edited recipients, the module deletes the existing forward and creates a new one with the new values. Please note here as well, entries need to be comma separated.
Important additional note: After clicking the "Confirm" button, 2 API call are fired. The 1st deletes the whole existing forwarder and the 2nd creates a new one the the new recipients. In case the recipient entry list is invalid (for example not comma separated, you'll loose the existing forwarder! It can be re-created afterwards but it's important to provide a valid entry here
Please note: In the edit mode you can just edit the recipients but not the forwarder address itself. If you want another (additional) address please create a new one and/or delete the old one.
