Maybe I'm not on top form today, but how does the *poster* get unsubscribed in this situation?
I can see how recipients behind non-8-bit mail paths could get unsubbed given a number of bounces, but the poster??

I suppose that is why best practices in this area is to transcode when you
connect to something which is not 8-bit clean, but never otherwise.
Not doing it might of course be a good way to rid the net of a bit of
obsolete software... sites which are not able to be 8-bit clean must be
really rare these days. I suppose somebody still has a PDP-8 or something
running, and it does have a certain historical interest, but most
protocols in wide use today assume an 8-bit clean transmission path. You
cannot use http on a 7-bit system, for instance.
