I realize you respect the capability of Russian hackers. But before you ask for Russian help I’d asking the US FBI first. They have been very effective art retrieving previously detailed emails, either by recovering them directly from the server or rebuilding them from the inevitable trip emails leave.
In fact the FBI is so adept at doing this that they’ve already done so. As mentioned in the FBI Director’s details on the investigation they recovered and rebuilt the deleted emails. I don’t think they need help from Russia but I’m sure they appreciate you looking after them…
All the best,
