+.BR raw " (default for a single part, see \-\-part)"
+
+For a message, the original, raw content of the email message is
+output. Consumers of this format should expect to implement MIME
+decoding and similar functions.
+
+For a single part (\-\-part) the raw part content is output after
+performing any necessary MIME decoding.
+
+The raw format must only be used with search terms matching single
+message.

+
+Output the single decoded MIME part N of a single message. The search
+terms must match only a single message. Message parts are numbered in
+a depth-first walk of the message MIME structure, and are identified
+in the 'json' or 'text' output formats.

+Compute and report the validity of any MIME cryptographic signatures
+found in the selected content (ie. "multipart/signed" parts). Status
+of the signature will be reported (currently only supported with
+--format=json), and the multipart/signed part will be replaced by the
+signed data.
