 Changes in 'master' (not in a release yet) (20XX/XX/XX)
 --------------------------
+   - Use the concise Spanish "MX de respaldo" label for Backup MX in domain lists and forms.
  
    - Treat recipient_delimiter as a set of alternative characters, matching Postfix behavior (see #1143, thanks @MatzeKitt).
    - Allow mailbox users to edit their own display name in the users/ interface when enabled globally or for selected domains; apply the same name validation to administrative mailbox creation and editing (see #1176, thanks @pvdv and @TrapoSAMA).
