Not necessarily. If the list adds List-* headers, but does not change
the subject nor the body, and the DKIM signature does not include
headers that are changed/included by the mailing list, then DKIM works fine.
For example, I've sent mails DKIM-signed mails to the Debian mailing
lists that are perfectly valid. After I removed some List-* headers from
the list of signed headers, that is.
(Reply-To might be a problem. It just so happens that the list in
question does not change it, but many do. I don't know if it's in the
default list of signed headers.)
