Under suveillance or not?

Today I dicovered for myself a new post service. You can order special mailboxes which you use for different purposes. This service can be interesting first of all for those who care about their privacy and prefare to keep their address private:) This company operates in US, Ireland, Canada, Switzerland and other places of the world.

What was surprising, it's the following quote:

Postal authorities use a little known surveillance technique known as the "mail cover", which operates informally and allows them to investigate your mail without having to first obtain a court order, a requirement in most countries. 'The mail cover' is simply an instruction to the mail carrier requesting that they note the return addresses on mail delivered to any address under investigation.

Normally you don't think that your mails are under surveillance. But in fact, I think, it happens quite often. Especially in certain states. No Demand - Do Supply, as they say in economics. :) Yesterday one my friend told me that his American friends never use Gmail, as they are unaware about their privacy and they never know when stored information can be used against them... Quite interesting.
