Update on this (sorry for the top post),

So we are going to move forward with Python 3 only and will be dropping
Python 2 support in next major release for each components.

I am (slowly) working through the test suite to improve the coverage so
that nothing breaks when we move to Python 3. There are already some
pending merge requests from Simon (thank you!) on both Django-Mailman 3
and Postorius. Once I am done with tests, I will dig in to review them
both and co-ordinate with Simon to land them.

thanks,
Abhilash
