Filtermail 0.5 deployment from #831 stores rejected messages in /tmp/filtermail-rejected and all of them appear to be MAILER-DAEMON messages. E.g. arcanechat.me sends messages about failing to deliver to users that are over quota without DKIM signature.
It seems to be a problem with our postfix configuration, there is a question on stackoverflow with a solution:

We need to run bounce messages through OpenDKIM milter so it signs outgoing messages, and make sure outgoing filtermail does not reject bounce messages because they are unencrypted.
