The qrunners are started by mailmanctl which shoud be started as root
but then sets itself to the user:group that were configured with the
configure options --with-username and --with-groupname. These default to
'mailman'. You can find the values in Defaults.py in the settings for
MAILMAN_USER and MAILMAN_GROUP

The web server is a persistent process, it's user:group on Ubuntu are
usually www_data, however, the web server invokes a CGI wrapper, e.g.
/var/lib/mailman/cgi-bin/admin which should be SETGID and group =
Mailman's group.

This is a secondary error because of the inability to write the real
error to the error log. Is the error log writable by Mailman's group?

Is there something like apparmor preventing access?
