This plugin looks for URLs shortened by a list of URL shortening services. Upon finding a matching URL, plugin will send a HTTP request to the shortening service and retrieve the Location-header which points to the actual shortened URL. It then adds this URL to the list of URIs extracted by SpamAssassin which can then be accessed by uri rules and plugins such as URIDNSBL.
