[py3] Pass bytes as "msg" to smtplib.SMTP.sendmail() When passing a unicode string to smtplib.SMTP.sendmail() as "msg" argument, there is an implicit bytes encoding using "ascii" encoding in python3. Of course this does not work if the string contains non-ASCII characters. In fact, config's sendmails method intent to pass bytes to smtplib.SMTP.sendmail() as it uses msg.as_string() method. Unfortunately, in python3, this method returns a unicode string whereas it returns a bytes string in python2; we thus fix this by calling as_bytes() method on python3. As there is no "as_bytes" method in python2, we need to handle python2 compatibility by hand and either call as_string() or as_bytes(). In testlib, where we mock smtplib.SMTP, we need to keep the "msg" argument of Email class (defined in testlib as well) a unicode string. Otherwise, it fails to be parsed by email.message_from_string() (from stdlib) if it is bytes on python3.
