Hello,
I know that no-one is allowed or cares enough to open up and read the mail that you are sending to someone via classic snail-mail. However, is it true that the postal service takes photos of the letters' envelopes and, apart from that, is there any other database being filled when it comes to sending mail? Because I feel like it would be strange for classic mail to be completely unregulated, but then again it would probably take massive amounts of resources to register all mail that goes through the service. For example, can they check who sent mail to whom 6 months ago if, let's say, the police required that info? Just curious, I haven't actually sent classic mail in a year.
I didn't find the right solution from the internet.
