:synopsis: Encoders for email message payloads.
When creating :class:`Message` objects from scratch, you often need to encode
the payloads for transport through compliant mail servers. This is especially
true for :mimetype:`image/\*` and :mimetype:`text/\*` type messages containing
binary data.
When creating :class:`~email.message.Message` objects from scratch, you often
need to encode the payloads for transport through compliant mail servers. This
is especially true for :mimetype:`image/\*` and :mimetype:`text/\*` type messages
containing binary data.
The :mod:`email` package provides some convenient encodings in its
:mod:`encoders` module. These encoders are actually used by the
:class:`MIMEAudio` and :class:`MIMEImage` class constructors to provide default
encodings. All encoder functions take exactly one argument, the message object
to encode. They usually extract the payload, encode it, and reset the payload
to this newly encoded value. They should also set the
:mailheader:`Content-Transfer-Encoding` header as appropriate.
