Search the log for all events associated with this smtp session, including the logged 'connect'. Then check timestamps - perhaps dkim-milter took long to respond and Postfix gave up waiting (although it would normally say so, but perhaps unix socket behaves differently than inet socket in this respect, I haven't tried). > One second later my backup MX which runs the same dkim-milter and > Postfix versions successfully received the message and forwarded > it to the primary mail server where it was received just fine. > Unfortunately the message has been deleted in the meantime > but I'm quite sure it was [1]this message which seems to have > a missing or null body.

If you manage to reproduce the problem, capturing a milter session with tcpdump (full size packets, binary) could be of help.
