The new option services.postfix.localRecipients allows configuring the postfix option 'local_recipient_maps'. When set to a list of user names (or patterns), that map effectively replaces the lookup in the system's user database that's used by default to determine which local users are valid. This option is useful to explicitly set local users that are allowed to receive e-mail from the outside world. For local injection i.e. via the 'sendmail' command this option has no effect.
