That's an unusual result. It might happen that a message gets corrupted, an subsequent verifications fail. The other way around is very unlikely. > What does body hash mismatch mean? Perhaps there are some headers not > checked by SA but are checked with zdkimfilter? The body hash is SHA-1 of the body, ignoring empty lines at the end of it ("simple" hashing algorithm). Zdkimfilter assumes Unix-style line endings and reinserts CR chars at line ends. > Spamassassin is run through pythonfilter-1.8.

The signed header fields are those indicated by the h= tag. In this case: to, subject, date, from, reply-to, message-id, mime-version, and content-type. back later... ------------------------------------------------------------------------------ See everything from the browser to the database with AppDynamics Get end-to-end visibility with application monitoring from AppDynamics Isolate bottlenecks and diagnose root cause in seconds.
