That's great.  (I thought you rejected idea to move to 3.0.)

I tried to do it around getmail 5.5 days.  (I didn't finish it)

I understand.  When I tried to convert this to Python3, the first thing
I did was clean out all backward compatibility codes, too.  It is too
much work to keep them.

Also if it is Python3 only, we don't need to add things like:

from __future__ import division
 from future import standard_library

If you have a public git repository, maybe some Debian developer may
help you.  If you want, I can set up one at salsa.debian.org (or
github.com) where ever you are comfortable.

At least, if we have a place to share work in progress, we don't
duplicate efforts.
