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).

Note that there isn't any LDOSUBSCRIBER in the headers of this mail.

Sorry, I was probably less than precise. 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.

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. No Ccs needed. :)
