[Colin Turner]

Package: mailman3-core
Version: 3.1.1-4
Severity: normal

Dear Maintainers,

Thanks so much for your work on these packages, and responses to previous bugs.

I tried another fresh install, using sqlite as a backend. I still get cron related permissions problems as below, once a minute:

Traceback (most recent call last):
 File "/usr/bin/django-admin", line 21, in <module>
   management.execute_from_command_line()

   '%r: %s' % (name, e))
ValueError: Unable to configure handler 'file': [Errno 13] Permission denied: '/var/log/mailman3/mailman-suite.log'

The permissions on the installed log directory and its current contents are as follows:

colin at oldgondolin:/var/log$ ls -al mailman3
total 80
drwxr-xr-x  2 list     list      4096 Mar  1 15:05 .

-rw-rw----  1 list     list         0 Mar  1 15:04 smtp.log


It may be worth mentioning that mailman2 is installed on this box.

Kind regards,

CT.
