Bitnami OpenProject 4.0.4-1.

delayed_job is now running, thanks to Bitnami support.
I read every guide on email configuration:

http://email.about.com/od/accessinggmail/f/Gmail_SMTP_Settings.htm
http://redmineblog.com/articles/setup-redmine-to-send-email-using-gmail/
https://community.openproject.org/topics/441
https://github.com/opf/openproject/blob/dev/doc/CONFIGURATION.md
https://wiki.bitnami.com/Applications/Bitnami_OpenProject#How_to_configure_the_email_settings_of_openproject.3f

I tried Gmail account and local intranet smtp, I always have this error in openproject production log file:

Completed 500 Internal Server Error in 279.3ms Errno::ECONNREFUSED (Connection refused - connect(2)): app/models/work_package_observer.rb:38:in `block in after_create' app/models/work_package_observer.rb:37:in `each' app/models/work_package_observer.rb:37:in `after_create'

Or something like this (I deleted the real email):

Sent mail to [[[[[[my email]]]]] (5.4ms) 2015-01-16T16:50:18+0000: [Worker(delayed_job host:linux pid:3592)] Class#work_package_updated failed with Errno::ECONNREFUSED: Connection refused - connect(2) - 3 failed attempts Rendered user_mailer/_issue_details.html.erb (6.7ms) Rendered user_mailer/work_package_updated.html.erb within layouts/user_mailer (26.0ms) Rendered user_mailer/_issue_details.text.erb (2.4ms) Rendered user_mailer/work_package_updated.text.erb within layouts/user_mailer (12.4ms)

I made many tests with different configurations.

For gmail, here my production section in the configuration.yml file:

production:
  email_delivery_method: "smtp"
  smtp_address: "smtp.gmail.com"
  smtp_port: 587
  smtp_domain: "smtp.gmail.com"
  smtp_user_name: myemail@gmail.com
  smtp_password: mypassword
  smtp_enable_starttls_auto: true
  smtp_authentication: :plain

I added this line at the end of the standard file.
I triple checked the email and password.
The command “ping smtp.gmail.com” works well.

Any hint?
