我正在使用 Rails 4 和 Ruby 2.0.0 开发一个 rails 应用程序。我的联系页面中有一个表格，我想从该表格向管理员发送电子邮件。我选择使用 smtp，这是我的配置文件：

# config/initializers/setup_mail.rb
ActionMailer::Base.smtp_settings = {
    adress:               "smtp.gmail.com",
    port:                 587,
    domain:               "gmail.com",
    user_name:            "my-gmail-login@gmail.com",
    password:             "my-gmail-password",
    authentication:       :plain,
    enable_starttls_auto: true
}

ActionMailer::Base.default_url_options[:host] = "localhost:3000"

ActionMailer::Base.raise_delivery_errors = true

这是我的邮件控制器：

# mailers/user_mailer.rb
class UserMailer < ActionMailer::Base
  default from: "my-gmail-login@gmail.com"

  def welcome_email(user)
    @user = user
    @url = "localhost:3000/signin"
    mail(to:      user.email,
         subject: "Welcome")
  end
end

最后，我的邮件视图：

# app/views/user_mailer/welcome_mailer.html.erb
<h1>Congratulations "#{@user.firstname} #{@user.lastname}"</h1>

当我打开“$> rails 控制台”时，我输入以下内容：

$> UserMailer.welcome_email(User.first).deliver

鉴于 rails 文档http://guides.rubyonrails.org/action_mailer_basics.html，这就是我所需要的。不幸的是我有一个连接错误：

你知道这个错误可能来自哪里吗？以及如何解决？

谢谢您的帮助。

已解决：这是一个语法问题。在配置文件中，地址应该是地址！
