Action mailer not sending/receiving email rails 5
<p>I'm trying to create a simple blog (using rails 5) and want to send email updates when to users when I post something new. I'm trying to use actionmailer and I'm using devise to register users. I'm trying to set it up with just the first user initially. </p>

<p>When I look at my local server the email appears to be sending but it's not received. Any advice would be very welcome I've been stuck a while.</p>

<pre><code>    UserNotifierMailer#sample_email: processed outbound mail in 410.4ms

<p>My posts controller looks like this:</p>

<pre><code>def create
    @user = User.first
    @post = current_user.posts.build(post_params)
    if @post.save
      flash[:success] = "Your post has been created!"
      UserNotifierMailer.sample_email(@user).deliver
      redirect_to posts_path
    else
      flash[:alert] = "Your new post couldn't be created!  Please check the form."
      render :new
    end
  end
</code></pre>

<p>My mailer looks like this:</p>

<pre><code>class UserNotifierMailer &lt; ApplicationMailer
  default from: "from@example.com"
  def sample_email(user)
    @user = user
    @url = 'http://www.google.com'
    mail(to: @user.email, subject: 'Sample Email')
  end
end
</code></pre>

<p>and in my development.rb I have these settings:</p>

<pre><code>config.action_mailer.raise_delivery_errors = true
  config.action_mailer.perform_deliveries = true
  config.action_mailer.default_url_options = { host: 'localhost', port: 3000 }

  config.action_mailer.delivery_method = :smtp

  config.action_mailer.smtp_settings = {
    address: "smtp.gmail.com",
    port: 587,
    domain: "gmail.com",
    authentication: "plain",
    enable_starttls_auto: true,
    user_name: "my_gmail_username",
    password: "my_gmail_password"
  }
</code></pre>
