[CQ-Contest] QSLing

[DXer]

Just a guess...to let the sending bureau and/or ham know that they tried,
but were unable to deliver the cards, and make 'adjustments'. Something
like the post office returning undelivered mail, instead of round filling
them. I would not want QSL cards to be treated as 'junk mail'.

======================================

Why would anyone return unwanted cards?  It sure would have helped the
environmental impact by putting them in the recycling bin........Right?
