This is documentation about a configuration directive, which can be placed within Movable Type’s core configuration file, mt-config.cgi, to customize the behavior of the system.

This configuration directive allows you to limit outbound TrackBacks and TrackBack auto-discovery for the purposes of keeping your installation private.

Possible values include:

  • any (default) - Allows all regardless of destination
  • off - Prevents all regardless of destination
  • local - Allows only those requests/pings sent to weblogs within the same installation as the blog which initiated the action
  • selected - Allows all to one or more domains specified by the [OutboundTrackbackDomains][] setting.

This option is the configuration file counterpart to the settings found on System Overview » Settings.
