I agree it is best to deal with this at the receiving end if possible.

That said, I suppose this is similar to the "notmetoo" functionality,
and perhaps "notmetoo" could be extended to cover these cases, too, i.e.
ignore "to" and "cc" addresses as well as the "from" one when
distributing posts. It shouldn't be too hard (I wrote the notmetoo
functionality, so am fairly familiar with it.)

Open an enhancement request on the bug tracker and/or write a patch for
it if you like.
