Quoth Alejandro Colomar:
I've found now why my MUAs don't include you in the reply. I've seen the following header in your message. I don't know if this is something you configured your MUA to send, or if it's an accident. Please have a look. Mail-Followup-To: Alejandro Colomar <alx@xxxxxxxxxx>, Guillem Jover <guillem@xxxxxxxxxxx>, linux-man@xxxxxxxxxxxxxxx
The Mail-Followup-To header field is good and useful. And Mutt, for example, sends it by default, if you’re properly using `lists` and `subscribe`. “I’m subscribed to this list anyway, so you need not send followups to me separately as well.” More people should use and honor it.
