A post is considered to be from a list member if any of the headers in
the Defaults.py/mm_cfg.py SENDER_HEADERS setting contains a member
address. The default setting is
SENDER_HEADERS = ('from', None, 'reply-to', 'sender')
(None means the envelope sender). Assuming you have the default setting,
the sabishi.meister at charite.de address was either the envelope sender or
in Reply-To: or Sender:.
You could set
SENDER_HEADERS = ('from',)
in mm_cfg.py to test only the From: for list membership.
