Hi Aurelien,
I was trying out mailman-bundler and have setup a demo here 1. I notice that with 'USE_SSL=True' in development.py deployment settings, there is a redirect loop while logging in2. I had to disable it to deploy.
(The demo server still needs to be hooked up with postfix).
Also maybe you can configure your launchpad repo of mailman-bundler to handle bug reporting? I saw that it needs to be enabled for individual repositories.
thanks, Abhilash
