There is a very disappointing news for all current and past users, US Federal Bureau of Investigation (FBI) has a complete copy of Tormail server and they are using it to catch the Criminals & Hackers.
According to court ********s that recently surfaced, the FBI have cloned the entire email database while investigating Freedom Hosting.
In August 2013, when the FBI seized the Tor network's top web host, Freedom Hosting, that gave the feds access to every record of every anonymous site hosted by Freedom Hosting, including TorMail, a service that allowed to send and receive email anonymously.
New evidence uncovered by Wired suggests those archives are now being used in completely unrelated investigations, but possibly now the FBI is mining the information from that database to track cyber criminals.
* Tormail was not affiliated with the Tor Project, a popular tor anonymity tool and browser, so Tor users should not be affected by the Tormail seizure.
