Hello,

i set up a openproject on an ubuntu 14.04 server according to the manual installation guide
https://www.openproject.org/open-source/download/manual-installation-guide/

Everything is working fine so far except the email notifications on task updates

First of all the cronjob described in the manual installation guide seems to be wrong
/1 * * * cd /home/openproject/openproject-ce; /home/openproject/.rvm/gems/ruby-2.1.5/wrappers/rake jobs:workoff

due to ruby 2.3.0 version installed prior via rbenv ( all according to the manual installation guides )

How does the correct cronjob look like?

Starting it manually fails aswell

root@project:# su project —login
project@project:$ cd openproject-ce/
project@project:~/openproject-ce$ RAILSENV=production bundle exec rake jobs:workoff

Appreciating any help what i am doing wrong here, if any more info is needed please tell me.

Test emails via admin account and upon new account creating are working but if i understood it correctly these are not processed via the worker job but send directly.

With kind regards
