Surely low power PIR sensor would work. Something like this maybe? https://www.youtube.com/watch?v=HGZFg4SVySM https://www.youtube.com/watch?v=HGZFg4SVySM

A light sensor on an ESP taped to the inside of the mailbox would probably work, and a note to the postal carrier informing them of its function, but I suspect you'd have issues with the range of the device.

  Yeah, I live 3 floors up and on the other side of the building from the mailboxes.
