I see where is the problem: Your mail client (mutt I suppose) sets
Mail-Followup-To header to all recipients (To and Cc) without the
sender. And my client (thunderbird) after pressing "Reply-All" checks
for Mail-Followup-To field, if present it uses only it to set
recipients, so in your case it does not response to the original author.

I do not know which mail client works incorrectly in this case, but for
sure it is not what we want :)

I do not know how to solve the issue in thunderbird, maybe mutt is more
