Benny,
It's their subject munging that breaks your dkim signature.
Try creating your message with that '[sanesecurity]' tag already in your subject
so that will be incorporated in your dkim signature.
(that or exclude the subject header from your dkim signatures).
This same issue will arise with any signed message sent to any list that insists
on doing subject munging.
I ran into a similar issue with mail relaying thru a MS Exchange server, it
insisted on stripping the numeric timezone value from the Date header field thus
breaking dkim signatures.
