It's a problem with all mailing lists that DKIM signatures get
corrupted, because the headers are altered.  DMARC and SPF don't help,
either. 

However, the From: header is never changed.  (The MAIL FROM: at SMTP
time is set to an address belonging to the list so the mailing list
software can process bounces: otherwise the poster would get all the
bounces.)

GMail are a law unto themselves when it comes to interacting with other
mail systems.  My advice is generally to just avoid using them, but this
sadly isn't always possible.

Perhaps if everybody fishes them out of their spam folder GMail's insane
spam filter will figure it out.
