offlineimap is python2 which is troublesome with modoboa on python3 #61

offlineimap does not fully support python3 and never will. See issues (github) and documentation (website).

Python3 is the only current supported Python: https://www.python.org/doc/sunset-python-2/ So hopefully Modoboa is running in a Python3 environment. If you do, you run into problems due to libraries/dependencies. This can be overcome with a wrapper script:

.offlineimap.py 

# offlineimap executes as Python2 which is troublesome
# we need to use python3 in a virtualenv
#import sys
import os

pyint = "/srv/modoboa/env/bin/python3"

cmd = pyint + " " + "~/offlineimap.py"

os.system(cmd)

where the original .offlineimap.py as published in the ReadMe.md section Helper script on https://github.com/modoboa/modoboa-imap-migration is now stored as offlineimap.py. see: https://github.com/modoboa/modoboa-imap-migration#helper-script-for-offlineimap

my cron entry looks like:

# offlineimap sync
0   */1 *   *   *   modoboa cd /vmail && $PYTHON $INSTANCE/manage.py generate_offlineimap_config --output /vmail/.offlineimaprc && offlineimap -c /vmail/.offlineimaprc > /dev/null 2>&1

Chances are this fix will not do the trick. After battling with a self-signed cert I get:

The problem is here that the "name 'get_user_password' is not defined" is not entirely true. It is defined in Python3 but not in Python2.
