Force a bunch of users to send mail only to a list of domains

NethServer Version: 7.6.1810 Module: mail 2.4.5-1 In [ Email Addresses ] -> [ username@domain.local ] -> [ Edit ] -> [ Local network only ] You can restrict email sending to local domain. I want to change that (or create another checkbox to do this), and instead limit that user to only sending emails to *.cu mails. How can I accomplish this ?
