Yes, even in network environments (e.g. VPN) where Mail Privacy Protection doesn't work, MailTrackerBlocker will still block and identify trackers if you choose to "Load Remote Content".
Note: Mail Privacy Protection's proxy will still fetch the tracker image, triggering the tracker after an unknown period of time. In the period of time before this happens, if you open your email without MailTrackerBlocker, the proxy will fetch the tracking image and trigger the tracker at that moment still letting the tracker know your exact opening time.
