Yes, I was aware.  And yes, when I let people know, they are
indeed shocked and offended.  As yet however the text of the
contents of paper mail is not routinely recorded.  Although
that could now be done with the appropriate spectrum of microwave
scanning and a sufficiently high-resolution receiver, I don't
think it could as yet be done without burning out the RFID's
that an increasing number of shippers are including for package
tracking, so there are conflicting goals there.

The same 'metadata' recording happens in all common publicly
accessible delivery services.  Fedex, UPS, etc do it too.

This is especially interesting in light of rules requiring the
MAC address of network-capable devices to be printed on the
outside of the packaging.  If they can get a device's MAC, they
can review delivery records to see to whom that device was sent.
