I have the following setup to send email at sign up:

Rails 3.0.7

ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-linux]

rails plugin install git://github.com/collectiveidea/action_mailer_optional_tls.git

Mailer 

class UserMailer < ActionMailer::Base

    def registration_confirmation(user)
    recipients  user.email
    from        "webmaster@example.com"
    subject     "Thank you for Registering"
    body        :user => user
    end
end

Controller:

   def create
    @user = User.new(params[:user])
    if @user.save
       UserMailer.deliver_registration_confirmation(@user)
       sign_in @user
       flash[:success] = "Welcome to ECE"
       redirect_to @user

      render 'new'
    end
   end

View:

Hi <%= @user.name %>, .....

I was getting smtp connection errors and I included this in gemfile after googling.

This is solved the error

Gemfile 

 gem 'rack-ssl', :require => 'rack/ssl'

Config/environment/development.rb

  config.action_mailer.raise_delivery_errors = true
  config.action_mailer.delivery_method = :smtp
  config.middleware.insert_before ActionDispatch::Static, "Rack::SSL"
  config.action_mailer.smtp_settings = {
     :enable_starttls_auto => true,
     :address        => 'smtp.gmail.com',
     :authentication => :login,
     :port           => 587,
     :domain         => 'www.example.com',
     :name           => 'user@gmail.com',
     :password       => 'password',
   }

Problem

earler I was getting 535-5.7.1 Username and Password not accepted.

Now it says:

SSL connection error

Unable to make a secure connection to the server. This may be a problem with the server, or it may be requiring a client authentication certificate that you don’t have.

Error 107 (net::ERR_SSL_PROTOCOL_ERROR): SSL protocol error.

Any suggestion?

    I’ve been using gmail for sending emails, and have never configured any extra gems. This is what I’ve in development.rb.

    config.action_mailer.smtp_settings = {
    :tls => true,
    :enable_starttls_auto => true,
    :address => "smtp.gmail.com",
    :port => "587",
    :domain => "domain.com",
    :authentication => :plain,
    :user_name => "user@domain.com",
    :password => "password"
}

    The points to be noted are:

    Note: The value for :domain is google apps domain. I think its not required if you are using the username which belongs to gmail.com.
