You need to set your user email before being able to send test emails

Hi,
I am getting "You need to set your user email before being able to send test emails." when I send a Test email using send mode smpt or php.

I checked my smpt configuration and it is all fine.

Version

ownCloud 9.1.5 (stable)

config.php
'dbuser' => 'oc_ocadmin',
'dbpassword' => 'Nrwsor1vcjdib10qfPSK5FaF2SQrzO',
'logtimezone' => 'Europe/Ljubljana',
'installed' => true,

'appstore.experimental.enabled' => 'true',

'mail_smtpport' => '587',
'mail_smtphost' => 'smtp.ztm.si',

This sounds to me more that you don't have added your own e-mail address in the personal area of your ownCloud.
