AUTH LOGIN broken

[michele-comitini]

The strings to be encoded are:

• 'Username:'
• 'Password:'

Mind the ":" at the end!

That is not the only problem, at least for me.

Outlook 2016 cannot authenticate with AUTH LOGIN, because of the missing ":" and because 334 is sent as unicode over the wire, instead of plain ascii.

The ":" at the end and changing: encode_b64 to
def encode_b64(data):
'''Wrapper for b64encode, without having to struggle with bytestrings.'''
byte_string = data.encode('utf-8')
encoded = base64.b64encode(byte_string)
return encoded

makes it possible for me to let outlook 2016 connect
