I would cut off all ties with both of them. How dare he say those things to you. I would definatley make the police aware of it and ask them what you should do, then change your email and don't give it to either of them. If this is the type of person your daughter wishes to be spending time with, then I would have nothing to do with her.
I can't even imagine how this made you feel. What a sick distorted mind he has. I think the only thing I would do is forward the email to where she is living so they can see what kind of person she is chosing to have a relationship with.
