wip/offlineimap - Python 3 version of offlineimap

[Thomas Klausner <wiz%gatalith.at@localhost>]

Hi!

To hijack a quite old thread - I'm looking for testers for
wip/offlineimap, which is the Python 3 version of offlineimap.

Please try it out and let me know if you find problems. I'd like to
use this to replace mail/offlineimap.

Thanks,
 Thomas
