As friend I would like to make a point regarding ur case. U were wrong in opening an email ID in ur friends name, even if ur intentions were good. By doing this u have needlessly dragged ur friend into this case.
U could easily have made an anonymous email id and used the same. U could have mentioned this fact in the letter written by u, along with the reasons for not using ur own email id.
I’m not a lawyer, just a well wisher.
Hope u don’t mind me sharing my views in this regard.
