X-Sendfile is an IPS plugin that implements server X-Sendfile support into the software suite.
In short, it's a way of allowing PHP to tell your web server to deliver files to the client after proper authentication checks, logging and other application logic has been performed.
This is far more ideal than forcing PHP to handle file transfers directly, as your web server is much more efficient in regards to handling static file transfers.
