The Emacs
MIME library will respect the
use-hard-newlines variable (see Hard
and Soft Newlines) when encoding a message, and the
“format=flowed” Content-Type parameter when decoding
a message.
On encoding text, regardless of
use-hard-newlines, lines terminated by soft newline
characters are filled together and wrapped after the column
decided by fill-flowed-encode-column. Quotation
marks (matching ‘^>*
?’) are respected. The variable controls how
the text will look in a client that does not support flowed text,
the default is to wrap after 66 characters. If hard newline
characters are not present in the buffer, no flow encoding
occurs.
You can customize the value of the
mml-enable-flowed variable to enable or disable the
flowed encoding usage when newline characteres are present in the
buffer.
On decoding flowed text, lines with soft newline characters
are filled together and wrapped after the column decided by
fill-flowed-display-column. The default is to wrap
after fill-column.

format=flowed article will be displayed flowed.
