What I’ve observed from six years of informed delivery is that the sorting step that generates the images for informed delivery happens before the step that handles forwarding and return to sender.

I’m not sure that any of the cases are that big of a privacy breach: It’s more inline with either getting the neighbor’s mail in your mailbox (which in my experience happens at about the same rate) or getting previous residents‘ mail in your mailbox (although my current carrier, after checking with me, intercepts most of these on her own initiative so I don‘t have to deal with them).
