The OP had an attached screenshot which was removed by this lists
content filtering.

The screenshot was from MHS internet hosting <http://www.mhs.ch/> and
appears to be from a spam filter saying (in German and English) that the
received mail appeared to be spam and offering a "release" button
"Please click on the button below to identify your message as a regular
message".

Have the recipient whose ISP is generating these messages contact her
ISP and ask them how to whitelist this list mail, and if she can't do
it, remove her from the list.

In the mean time, if your list is digestable, you could switch the
subscriber to digests. The digests may still produce the notices, but
they will go to the list owner.

Also, have people receiving these tried clicking the "release" button.
