My email below got a DKIM issue.
It validated fine here, not a debian list issue.
For the record, I looked at the wrong email. The right one did fail
DKIM validation while passing through debian. (Note that it goes from
DKIM_VALID to DKIM_INVALID in what looks like two subsequent checks on
bendel.) On my system that one says that it fails dkim because the
body was altered. Looking at the body my best guess would be that it's
a normalization/line length issue on the part of the dkim signer, but
without the original message that's just a guess.
More information from the OP, it looks like the message sent to the list
was base64 encoded html. So I'm guessing that the list software
autoconverted that to plain text--which would mean there's no way to
preserve a valid DKIM signature.
