This seems relevant in the headers:

Authentication-Results: mx.google.com; dkim=neutral (body hash did not verify) header.i=@gmail.com; spf=pass (google.com: best guess record for domain of cake-bounces at lists.bufferbloat.net designates 45.79.142.77 as permitted sender) smtp.mailfrom=cake-bounces at lists.bufferbloat.net; dmarc=fail (p=NONE dis=NONE) header.from=gmail.com

I forget exactly how DKIM and DMARC work, but DKIM seems to be stymied by the list adding its own message footer (which is nevertheless best-practice).  I don’t know how relevant a DMARC fail is to their filter, or how relevant it *should* be.

Could the listserver replace an original, verified DKIM certificate with its own after adding the footer?

On the upside, I was able to add a filter specifically saying “never send to Spam folder”, and it appears to be working so far.  But everyone probably needs to do that; it’s not a scalable solution, only a workaround.
