Email is not delivering in rails app

I am trying to send email in my rails app and in logs I have seen following body

Subject: Ashish Singla is inviting you to read together...

but email is not delivering.

Answer 1

At least your mailer class is working. If you are in development mode, ensure that you have the perform_deliveries option set to true.

If not, go to your config/environments/development.rb file and write

config.action_mailer.perform_deliveries = true

If this setting is already set to true and you are not getting the emails, then probably your smtp settings are not properly set. You can set them in config/application.rb with something like following:

config.action_mailer.smtp_settings = {
  :address        => 'smtp.office365.com',
  :port           => 587,
  :domain         => 'your-domain.com',
  :user_name      => 'user@your-domain.com',
  :password       => 'somePassword',
  authentication: :login,
  enable_starttls_auto: true
}

In this case, may be enabling the setting raise_delivery_errors will help you to diagnose problems. You can do that in your config/environments/development.rb file and writing:

config.action_mailer.raise_delivery_errors = true

Then you will get an exception when the email can't be sent and (hopefully) a description about the problem.

And after reading your comment: after changing all these config settings, restart the delayed_job backend.
