Setup SMTP settings for sending mail in rails - ruby-on-rails

Question

I've followed the following tutorial to create a contact form.
Everything was fine, but as tutorial says For real e-mail delivery, you should set up SMTP in the environment settings. how can I set up SMTP?
As Suggested in this link I created and edited the smtp_settings.rb; But No luck at all. It still doesnot send the email to the real user.
smtp_settings.rb
if Rails.env.production?
Gitlab::Application.config.action_mailer.delivery_method = :smtp
ActionMailer::Base.smtp_settings = {
address: "smtp.gmail.com",
port: 587,
user_name: "myaccount#gmail.com",
password: "abcpassword",
domain: "mail.google.com",
authentication: :login,
enable_starttls_auto: true
}
end

It may be because your smtp_settings.rb file isn't being found by Rails, or that the delivery_method line isn't being recognised..
Try moving the file to /config/initializers/smtp_settings.rb if it isn't there already, and changing the contents slightly to
if Rails.env.production?
ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.smtp_settings = {
address: "smtp.gmail.com",
port: 587,
user_name: "myaccount#gmail.com",
password: "abcpassword",
domain: "mail.google.com",
authentication: :login,
enable_starttls_auto: true
}
end
It could also be that the settings are only applied for production, if you're trying this out locally in development you'll need to remove the first line if Rails... and the last line end like so..
ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.smtp_settings = {
address: "smtp.gmail.com",
port: 587,
user_name: "myaccount#gmail.com",
password: "abcpassword",
domain: "mail.google.com",
authentication: :login,
enable_starttls_auto: true
}
After any changes to this file you'll need to restart your rails server or rails console session for the changes to take effect.
