Then NR is broken. When I send a message to ietf-822@xxxxxxx, I do _not_
want followups to be sent to the original reply address. That's why my
message says Mail-Followup-To: ietf-822@xxxxxxxx

(The Mail-Followup-To is inserted automatically, of course. The only
manual effort was a long time ago, putting ietf-822@xxxxxxx into
$HOME/.lists and setting QMAILMFTFILE to $HOME/.lists.)

Then you are fundamentally confused about what mail users want to do.
