[Mailman-Developers] Why is postorius using python2?

Hi there,

I just downloaded the mailman3 code to see if I can contribute anything. I was astonished to find out that postorius still uses python2 although mailman made the switch to python3. Is there any reason behind this? I asked on the irc channel but got no answer so I'm trying here.

I used 2to3 on the code and successfully executed the code.

I executed the tests, and ran into some errors. If this work is going to be included sometime, I'm willing to investigate and try to fix these errors.
