This basic generator writes the message to the given file object as plain text. iNcCs||_||_||_dS(sáCreate the generator for message flattening. outfp is the output file-like object for writing the message to. It must have a write() method. Optional mangle_from_ is a flag that, when True (the default), escapes From_ lines in the body of the message by putting a `>' in front of them. Optional maxheaderlen specifies the longest length for a non-continued header. When a header line is longer (in characters, with tabs expanded to 8 spaces) than maxheaderlen, the header will split as defined in the Header class. Set maxheaderlen to zero to disable header wrapping. The default is 78, as recommended (but not required) by RFC 2822.
