I don't see how any of this is relevant. I also don't see any quotes from RFC 2822.

Should my MUA stop me from sending a response to the Sender address? If it does not stop me, should it provide no easy way to do this? If it provides an easy way to do this, should it merely not use Sender by default? > The default reply address is the From field.

I don't think any of that is in dispute. paul
