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.

OneHourMaxPings and OneDayMaxPings settings allow you to limit the maximum number of TrackBack pings that you will accept in the period of either one hour or one day, respectively. In fact, the latter limit applies to the period which is 4000 times as long as the ThrottleSeconds value, which defaults to 20. Thus, by adjusting the ThrottleSeconds value, you can change the amount of time during which the OneDayMaxPings setting applies.

A higher-than-usual rate of incoming TrackBack pings can be indicative of malicious behavior. These settings give you a measure of protection against such behavior.
