Anybody working on a solution to the mailing list problems (a.k.a JDK-8213225)?

The header has:

X-Content-Filtered-By: Mailman/MimeDel 2.1.17

I suspect it's the same issue I already mentioned: The text/html part
was stripped by the mailing list software.  Of course that changes the
message body, and so the DKIM signature no longer verifies.

The workaround is not send text/html multipart messages to the mailing
lists.
