I'm not familiar enough with the email package to answer that.

email.Generator and email.Message use cStringIO.StringIO internally, which
can't cope with unicode. A quick fix might be to monkey-patch:
from StringIO import StringIO
from email import Generator, Message
Generator.StringIO = Message.StringIO = StringIO
