This happens very rarely and its due to misconfigured email servers
which send us bad dkim signatures, including bad in the case that they
include nonexistent list-* headers in their list of signed headers,
which should never be done. In this case, the dkim signature failed to
verify when it got to our server, so we had to rewrite it.

[verification failed - signature did not verify (headers probably modified in 
transit)]

I'm planning to implement an autoreply in such cases to let the posters
know to fix their mail server.
