Confirmation: when Arch Linux forwards a base8 encoded email to the list, it mangles the DKIM. It does appear to be an Arch problem!
One last email: what the lists are specifically doing is rewriting 8bit encoded emails in a base64 encoding. From the email in my sent folder:
Content-Transfer-Encoding: 8bit
From the email I received from the list:
Content-Transfer-Encoding: base64
Rewriting the body in a new encoding breaks DKIM. Jaron
