I did a manual installation of OP5 on ubuntu 14.04 with PLESK 12.5

Everything works fine except for the email system. I am able to send a testmail.

When I create a new user …. no email is send
When I update a workpakkage ….. no email is send

configuration.yml:

1. default configuration options for all environments
   default:
   # Outgoing emails configuration (see examples above)
   email_delivery_method: smtp
   smtp_address: example.nl
   smtp_port: 25
   smtp_domain: example.nl
   smtp_authentication: login
   smtp_user_name: “openproject@example.nl”
   smtp_password: “****”

When I run the worker for delayed jobs I get the following error:

[Worker(host)] Starting job worker
[Worker(host)] Job DeliverInvitationJob (id=17) RUNNING
[Worker(host)] Job DeliverInvitationJob (id=17) FAILED (0 prior attempts) with RuntimeError: Invalid delivery method :letter_opener
[Worker(host)] 1 jobs processed at 4.1106 j/s, 1 failed
[Worker(host)] No more jobs available. Exiting

Anybody any ideas???

Fixed the problem.

Found that the letter-opener was only used in Development mode.
By adding RAILS_ENV=production to the cronjob Openproject started to send mails.

cronjob now looks like this:
cd ~/openproject-ce; RAILS_ENV=production /var/www/vhosts/pmtool.nl/.rbenv/shims/bundle exec rake jobs:workoff

I now wonder if i’m running Openproject in development mode? how to run it in production mode?
