I have not tried myself the following suggestions from another mail 
list, so I do not know real value of them or non-obvious drawbacks:

1. Use "duplicate" sieve extension. FRC7352 (not 7353). It is supported 
e.g. by dovecot
https://tools.ietf.org/html/rfc7352 Sieve Email Filtering: Detecting 
Duplicate Deliveries
https://wiki2.dovecot.org/Pigeonhole/Sieve/Extensions/Duplicate 
Pigeonhole Sieve: Duplicate Extension

2. Just add filter that drops messages having mail list in To or Cc but 
have not passed mail list server.
