See:

    https://docs.python.org/3/library/email.generator.html#module-email.generator

While is conservatively writes ASCII (and email has extensive support 
for encoding other character sets into ASCII), you might profit by 
looking at the BytesGenerator in that module using the policy parameter, 
which looks like it tunes the behaviour of the flatten method.

I have a mailfiler of my own, which copes just fine.

It loads messages with email.parser.Parser, whose .parse() method 
returns a Message, and Message.as_string() seems to write happily into a 
text file for me. I run _all_ my messages through this stuff.
