"The central class in the :mod:`email` package is the :class:`Message` class, "

"imported from the :mod:`email.message` module. It is the base class for "

"the :mod:`email` object model. :class:`Message` provides the core "

"functionality for setting and querying header fields, and for accessing "

"message bodies."

msgstr ""

#: ../../library/email.message.rst:13

msgid ""

"Conceptually, a :class:`Message` object consists of *headers* and "

"*payloads*. Headers are :rfc:`2822` style field names and values where the "

"field name and value are separated by a colon. The colon is not part of "

"either the field name or the field value."

msgstr ""

#: ../../library/email.message.rst:18

msgid ""

"Headers are stored and returned in case-preserving form but are matched case-"

"insensitively. There may also be a single envelope header, also known as "

"the *Unix-From* header or the ``From_`` header. The payload is either a "

"string in the case of simple message objects or a list of :class:`Message` "

"objects for MIME container documents (e.g. :mimetype:`multipart/\\*` and :"

"mimetype:`message/rfc822`)."

msgstr ""

#: ../../library/email.message.rst:25

msgid ""

":class:`Message` objects provide a mapping style interface for accessing the "

"message headers, and an explicit interface for accessing both the headers "

"and the payload. It provides convenience methods for generating a flat text "

"representation of the message object tree, for accessing commonly used "

"header parameters, and for recursively walking over the object tree."
