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.meis...@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.

[Mailman-Users] Recent phishing mails are targeting mailing-lists -- and do pass

2017-09-25 Thread Ralf Hildebrandt
Recent phishing mails are targeting mailing-lists -- and do pass.

From our logs:
Sep 25 12:10:41 2017 (1940) post to rundmail-it from 
sabishi.meis...@charite.de, size=4760, 
message-id=<486320030245.201792592...@charite.de>, success

But the headers of the mail that was automatically passed (since
sabishi.meis...@charite.de is a member) was:

From: "Sabishi.Meister@"
