Hi, Somewhat in keeping with a cheeky question I asked the IAB at the last plenary, I want to ask some questions. These are not actually for John, though they hang off his message. The 2d person pronoun is directed at the reader of this message, not John.

Do you think that, given the various ways that this is now actually violated pretty widely around the Internet, the "integrity of the mail systems" is already lost? If so, does that mean that we have a new _de facto_ mail system emerging? If so, does that imply that we ought to document it in some documentation series?
