So my friend recently found something out that I really don't want him to tell someone. I have access to his computer and he intends to email them soon and tell them what he knows. He uses mozilla thunderbird on his laptop.
I need a way to stop him from either sending the message (without him knowing) or stop him from receiving a message back (without him knowing).
I know about filters but I am 99% sure he would check after not receiving a message for a while and I would be in shit.
Any help or way to make a hidden filter? I know the email address of the person he is trying to contact if that helps.
I really would prefer if I could someway blacklist them from sending emails to a certain address without them knowing.
