A message object is defined as something that has a bunch of RFC 2822 headers and a payload. It may optionally have an envelope header (a.k.a. Unix-From or From_ header). If the message is a container (i.e. a multipart or a message/rfc822), then the payload is a list of Message objects, otherwise it is a string. Message objects implement part of the `mapping' interface, which assumes there is exactly one occurrence of the header per message. Some headers do in fact appear multiple times (e.g. Received) and for those headers, you must use the explicit API to set or get all the headers. Not all of the mapping methods are implemented. cC`sV||_t|_d|_d|_d|_d|_|_g|_ d|_ dS(Nu text/plain( tpolicyRt_headersRt _unixfromt_payloadt_charsettpreambletepiloguetdefectst _default_type(tselfR0((sO/opt/alt/python27/lib/python2.7/site-packages/future/backports/email/message.pyt__init__|s      tencodinguutf-8cC`s |jS(uwReturn the entire formatted message as a string.
