A decent assumption but, unfortunately, not correct. I've come to the tentative conclusion that Debian can somehow link my envelope-from and the subscribed address via their A records (or something like that).

The 127.0.1.1 line in /etc/hosts is a FQDN and is used by exim for the HELO/EHLO. /etc/mailname determines the envelope-from. > > > Or is it because the first mail hop added "envelope-from" to its Received: > > > header ? > > > > > > Received: from ... by ... with local (Exim 4.89) > > > (envelope-from <...>) > > > id 1iHRiB-0006S7-Ks > > > for debian-user@lists.debian.org; Mon, 07 Oct 2019 13:01:59 > > > +0100 > > > > I can alter that too, and still be designated LDOSUBSCRIBER. > > Have we observed that?

What I altered was the HELO/EHLO; it made no difference. Altering the envelope-from did, but it would be unwise to assume I am not subscribed to the list and receiving all mails.
