Why should the recipient identify this entity? Those
postcard sites are
vulnerable to spoofing, let them fix their own problems.
Because Grandma might like to know which of her grandkids sent the
postcard.

Which still doesn't make sure it _is_ little jimmy sending the card.
If envelope-from is set to postcards(_at_)crummypostcards(_dot_)com, that domain
will have to deal with bounces, not jimmy(_at_)bitshift(_dot_)org
