python 3 + milter

[Nagy László Zsolt]

Does anyone know a module that can be used to write a before-queue,
smtpd time milter with Python 3?

Unfortunately, pymilter does not work with Python 3:

I have a complete program that works with email.Message messages, but I
don't know how to use it with postfix.

A workaround would be to construct the message from python2 + pymilter,
and start a subprocess for the message processing, but that is obviously
bad.

Thanks,
