I agree with everything you say.  I agree that the confirmation
request is 'essentially a bounce'.  TMDA carefully ensures that at the
SMTP level it is indistinguishable from a bounce.

But in a very real sense it's not a bounce.  It doesn't say "your
message was not delivered".  In some ways it's more akin to those
4-hour warnings that tell you that your mail hasn't been delivered so
far.

Granted, but it's no worse than sending the confirmation request in
the first place.

Sorry, I didn't realize those messages remained in pending.  Obviously
I only mean those messages in pending that were still pending :)

I guess that complicates the coding, though...

I wasn't accusing TMDA of throwing the principle out of the window.
It's the 'delete it if it matches a few patterns' people that have
thrown the principle out of the window.

I realize it's a somewhat subjective issue as to whether a second
bounce is necessary; I'm not asking for it to be the default, just
that it be an option.

In summary, I think there's a big difference between "please reply to
this, otherwise your message won't be delivered" and "you're message
wasn't delivered".  IMHO the latter is a bounce, the former may be
bounce-like, but it isn't a bounce.
