That's debatable. I was brought up on Earth.

About. But, curiosity led me to some old documentation.

Or the recipient could never get around to reading it.

I will give you one thing, the post office supposedly always delivers. But, they 
don't. Thieves get into mailboxes. And recognized spam finds its way into the 
trash "received" but unread. Any email system is very likely to suffer this same 
problem as thieves improve their hacking techniques. That's just one way things 
could go wrong. Do you presume PCBoard had no bugs or is that a demonstrated fact?
