can't unsubscribe because " <gstreamer-devel-request at lists.freedesktop.org>: Recipient address rejected: User unknown in local recipient table (in reply to RCPT TO command)"

Hi.

I tried to unsubscribe from the list via e-mail as it's shown in the list
Header.

```
List-Unsubscribe:
<https://lists.freedesktop.org/mailman/options/gstreamer-devel>,
<mailto:gstreamer-devel-request at lists.freedesktop.org?subject=unsubscribe>
```

I got the following answer from gabe.freedesktop.org.

```
<gstreamer-devel-request at lists.freedesktop.org>: host
    gabe.freedesktop.org[2610:10:20:722:a800:ff:fe36:1795] said: 550 5.1.1
    <gstreamer-devel-request at lists.freedesktop.org>: Recipient address
    rejected: User unknown in local recipient table (in reply to RCPT TO
    command)
```

Should it be possible to unsubscribe from the list via e-mail commands?

Regards
Alex
