[Pkg-mailman-hackers] Bug#891849: Cron errors, permission denied: '/var/log/mailman3/mailman-suite.log'

[Markus Gschwendt]

i tried to fix this with

chown list:list /var/log/mailman3/mailman-suite.log

but then other parts break:

```
Traceback (most recent call last):
  File "manage.py", line 10, in <module>

    '%r: %s' % (name, e))
ValueError: Unable to configure handler 'file': [Errno 13] Permission

```

I think that 2 different users try to write to that logfile.

A workaround (i don't like) is to give o+rw permission to that file.
