That is the issue for me. The other aspects of DSN are mostly harmless.
But it is the general use for checking that a message has been delivered
that I find objectionable.

    (1) First, it will never be reliable, due to difficulty in defining
        "delivery", and for non-uniform implementation.  There will be
        far too many false positives and false negatives.


    (2) If it is not highly relieble (see (1)) it is quiet probably worse
        than useless.


    (3) It can nearly double the number of messages transmitted, while
        being useless in terms of informativeness.
