Well, you use an MUA (Thunderbird) which does a decent job of reporting
errors.

Statistical anomalies (including most of us on this list) aside, everyone
uses Outlook or Outlook Express, which are cleverly designed to cause great
frustration when they get rejected. [One common result is the "I can't get
my mail" support call, since sending is tried before receiving and the
rejection is well hidden by default.]

If one knows that one's sender population uses sensible MUAs, the game
changes.
