PS:
Without those headers, a lot of MUA mailing list features don't work,
also filtering doesn't work and for some MUAs, such as Claws even a
"reply to all" workaround doesn't work, since the mailing list reply is
invoked by a reply:
List-Id: A list for linux audio users <linux-audio-user.lists.linuxaudio.org>
List-Unsubscribe: <https://lists.linuxaudio.org/options/linux-audio-user>,
<mailto:linux-audio-user-request@lists.linuxaudio.org?subject=unsubscribe>
List-Archive: <https://lists.linuxaudio.org/archives/linux-audio-user>
List-Post: <mailto:linux-audio-user@lists.linuxaudio.org>
List-Help: <mailto:linux-audio-user-request@lists.linuxaudio.org?subject=help>
List-Subscribe: <https://lists.linuxaudio.org/listinfo/linux-audio-user>,
<mailto:linux-audio-user-request@lists.linuxaudio.org?subject=subscribe>
On many mailing lists most, if not all subscribers would ask you to
stop replying directly. It's common to reply to mailing löists only,
even on a lot of open mailing lists.
