If one is filtering mail selecting for mail through a mailing list
then one should not use the To: or Cc: for that filtering. The best
and expected header to use is the List-Id: header. That's the
standard mailing list header. See RFC2929.
RFC 2929 https://tools.ietf.org/html/rfc2919
All mail through this mailing list sets this header.
List-Id: Postfix users <postfix-users@postfix.org>

P.S. It's a little strange to see an '@' in the List-Id. But other
than mentioning it in passing I am going to ignore it. :-)
