Pip install requires deprecated distribute package (Python3.3)

An install of pyzmail with pip fails to install.

Workaround requires installing the deprecated distribute package, as said in above forum post.

As I can understand, the code requires this to convert code with 2to3.py. Why not rewrite the code to conform to Python3.x specification?

I will look into this, if code is valuable for my project, I'll probably start a fork to rewrite the code, or maybe find someone beating me to it... :-)
