Might have been asked already but has he provided evidence that he has actually read your emails, has he provided specific details, besides emails you have been in communication with his partner about? He sounds like a lunatic who is just making threats and saying he has been hacking you when he hasn't and such like. He's probably just been reading the emails you've sent to his partner and the nasty little psycho fuck has created some chaos by creating a shitty story. Report the little scrote to the bizzies.
