Hello,
I've been through DKIM hell and back. Now I'm to the point where when I "show original" mail with gmail it says SPF, DKIM and DMARC all pass, but it's still going to the spam folders.
Does your list domain publish a DMARC record? If not publishing a DMARC record with policy of none may help, but it seems you are probably doing that.
Beyond that, it is probably filtering based on something in the message content and the recipient ISPs will never tell you what because they consider that kind of information proprietary.
Setting up feedback loops with gmail and yahoo also may help, but there's really not much else you can do.
