**raw** (default for a single part, see --part)
For a message or an attached message part, the original, raw
content of the email message is output. Consumers of this
format should expect to implement MIME decoding and similar
functions.
**raw** (default if --part is given)
Write the raw bytes of the given MIME part of a message to
standard out. For this format, it is an error to specify a
query that matches more than one message.
For a single part (--part) the raw part content is output
after performing any necessary MIME decoding. Note that
messages with a simple body still have two parts: part 0 is
the whole message and part 1 is the body.
If the specified part is a leaf part, this outputs the
body of the part after performing content transfer
decoding (but no charset conversion). This is suitable for
saving attachments, for example.
For a multipart part, the part headers and body (including
all child parts) is output.
The raw format must only be used with search terms matching
single message.
For a multipart or message part, the output includes the
part headers as well as the body (including all child
parts). No decoding is performed because multipart and
message parts cannot have non-trivial content transfer
encoding. Consumers of this may need to implement MIME
decoding and similar functions.
