And, your disproofs are flawed. Outlook server, used in most corporate offices has back doors built into it. Thus, even if it is an internal email, it still may be sucked up. Same with the phone PBX.

We don't use Outlook. And as to the phone PBXes bullshit. We built them. ;) We didn't buy them from a manufacturer. Furthermore I gave you an example where people could make intraoffice phone calls without it even being connected to the rest of the world. Even if there was a back door it wouldn't do anything for you if the system isn't connected to the rest of the world for the back door to be accessed.

So my examples stand. There are a lot more email servers than outlook. In fact the SMTP protocol is pretty simple. I've written some of them before from scratch. No NSA code there.

My entire argument was based around the absolutes. It only takes one case for an absolute to be false. Thus what I said stands.

Email does not have to go onto the internet. LEt's say I am sending from the IT Department to the Accounting Department in the same company. That email will never even touch the internet.

There is no sucking thing that is constantly dragging all packets off of everyone's internet circuits. It doesn't happen. You can use wireshark (tshark) or anything like that an monitor the traffic.

I don't put any weight in the difference between most phone calls being recorded and all phone calls being recorded.

One is possible. The other is not.
