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.
