Configure IBM Aspera Faspex to allow external senders, those who
            do not have Faspex accounts, to send packages to Faspex users. 
        - 
                Go to Server > Configuration > Security and find the
                    Outside Email Addresses section.
            
 
- 
                Select Allow inviting external senders and set the
                    default to Allow.
                
When set to 
Allow, all Faspex users are able to
                    invite external senders by default. An Admin can enable or disable this
                    feature for specific users from the Accounts page, while retaining server-wide
                    settings. For instructions on inviting external users, see 
Inviting External Senders.
