But what is misconfigured in particular ?

The mail clients used are all different:
Lisi:       User-Agent: KMail/1.9.10    [gets no spam]
Michael:    User-Agent: Mozilla/5.0        [gets spam]
Charlie S:  X-Mailer: Claws Mail 3.13.2    [gets spam]
me:         Custom SMTP client          [gets no spam]

But the mail servers only get to see the mail headers, not the local
configuration of the mail client. So the difference would have to
show up in those headers.


All mails i get from the list have as first header

  Return-Path: <bounce-debian-user=scdbackup=gmx.net@lists.debian.org>

which is not by my mail client but obviously from the list server.
I assume that you see your own address as first header in the mails you
get from the list.

Different from mine, your, Michael's, and Charlie's mail clients seem
to have sent own Return-path headers which the list server converted to
  Old-Return-Path: <lisi.reisz@gmail.com>
  Old-Return-Path: <michael.e.milliman@gmail.com>
  Old-Return-Path: <taoquester@gmail.com>
So this cannot be the difference between your and their experience.


My best theory for now is that the spam sender has a list of spam-worthy
Gmail users and that lisi.reisz@gmail.com is not on it.
(What products are advertised in the spam part ? Typical male ?)


Have a nice day :)
