Why are emails not sending in my rails app? Internal Server Error) Ch 20. Learn Rails tutorial by Daniel Kehoe

Question

I am on Ch 20 of the Learn Rails tutorial 'Send Mail'. There is a create contact form and a notification email is supposed to be sent to my email address. I have set up configuration as per the book and the email is being generated correctly i the terminal log. however the email never sends to my email inbox. I am getting an internal server error. see below for details.

Completed 500 Internal Server Error in 30831ms



Net::OpenTimeout (execution expired):

app/controllers/contacts_controller.rb:10:in `create'

contacts_controller.rb

class ContactsController < ApplicationController

  def new
  @contact = Contact.new
  end

  def create
    @contact = Contact.new(secure_params)
    if @contact.valid?
      UserMailer.contact_email(@contact).deliver_now
      flash[:notice] = "Message sent from #{@contact.name}."
      redirect_to root_path
    else
      render :new
    end
  end

  private
    def secure_params
      params.require(:contact).permit(:name, :email, :content)
    end
end

user_mailer.rb

class UserMailer < ApplicationMailer
  default from: "do-not-reply@example.com"

  def contact_email(contact)
    @contact = contact
    mail(to: Rails.application.secrets.owner_email, from: @contact.email, :subject => "Website Contact")
  end

end

i also have my email address set in the config/secrets.yml file like so :

owner_email: <%= ENV["my_email_address@*******.com"] %>

I have also added the following to my .bashrc file as per the early chater of the book about configuration:

export SENDGRID_USERNAME="user_name"
export SENDGRID_PASSWORD="password"
export MAILCHIMP_API_KEY="long_random_api_key_here"
export MAILCHIMP_LIST_ID="list_id_here"
export OWNER_EMAIL="**********@*********.com"

so as far as i see i have set everything up according to the tutorial but the mail is not sending. any ideas why?

From the above share code description and log trace, it seems like mailer settings is not configured properly.

Note: You need to set the mailer settings based on the environment on which you are working(eg: development.rb)

Follow the below given link for the configuration of mailer settings:
