Actually, I don't think we disagree. Bruce was talking about automatic agents
and I somehow managed to conflate in my subsequent discussion of resending.

I do think that the further away you get from final delivery the less sense it
makes to have automatic resending agents. But I don't think there should be any
hard rules about this.

Absolutely. I do it myself all the time.

I think we need to deal with the removal of return-path in a more
general way that's not specific to resending.

Exactly.
