Delivered-To: www@cloud
From: root@cloud (Cron Daemon)

Steps to replicate it:

The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):

$CONFIG = array (
  'instanceid' => '',
  'passwordsalt' => '',
  'datadirectory' => '/mnt/bigdisk/nextcloud',
  'dbtype' => 'pgsql',
  'version' => '',
  'dbname' => 'nextcloud',
  'dbhost' => 'localhost',
  'dbtableprefix' => 'oc_',
  'dbuser' => '',
  'dbpassword' => '',
  'installed' => true,
  'maxZipInputSize' => 838860800,
  'allowZipDownload' => true,
  'theme' => '',
  'maintenance' => false,
  'trusted_domains' => 
  array (
    0 => 'cloud',
  'mail_smtpmode' => 'smtp',
  'secret' => '',
  'loglevel' => 2,
  'htaccess.RewriteBase' => '/',
  'mail_from_address' => 'cloud',

  'overwrite.cli.url' => 'https://cloud',
