我的开发.rb：

config.action_mailer.default_url_options = {:host => "localhost"}
config.action_mailer.delivery_method = :smtp
  config.action_mailer.perform_deliveries = true
config.action_mailer.smtp_settings = {
  adress: 'auth.smtp.1and1.fr',
  port: '587',
  user_name: 'foo@bar.fr',
  password: 'password',
  authentication: :plain,
  enable_starttls_auto: true}
  config.action_mailer.raise_delivery_errors = true

环境.rb：

# Load the Rails application.
require File.expand_path('../application', __FILE__)
ActionMailer::Base.default :content_type => "text/html"

# Initialize the Rails application.
Rails.application.initialize!

我的控制器（我发送电子邮件的命令）：

  def create
    @incident = Incident.new(incident_params)
    @incident.user_id ||= current_user.id
    @incident.incident_state_id_for_user = 1
    @incident.incident_state_id_for_tech = 1


    respond_to do |format|
      if @incident.save
    @response = Response.new(content: "Incident créé par #{current_user.name} #{current_user.surname}", incident_id: @incident.id, sender_id: @incident.user_id)
    @response.save!
        AppMailer.incident_created.deliver_now
        format.html { redirect_to @incident, notice: 'Incident crée.' }
        format.json { render :show, status: :created, location: @incident }
      else
        format.html { render :new }
        format.json { render json: @incident.errors, status: :unprocessable_entity }
      end
    end
  end

App_mailer.rb：类 AppMailer

  default from: "foo@bar.fr"

  def incident_created()

    mail(to: "bar@baz.com", subject: "Succefull !", body: "You're really cool!")

  end

end

还有application_mailer.rb：

class ApplicationMailer < ActionMailer::Base
  default from: "foo@bar.fr" #Here is a fake mail adress
  layout 'mailer'
end

所以我使用 LinuxMint 17.2、Server Puma on rails、rails 4.2.3 ...

编辑：我尝试使用 telnet auth.smtp.1and1.fr 587 ping 服务器，它可以工作

我尝试将端口更改为：25 和 465，但它不起作用

【问题讨论】：

它看起来像是一个错误的主机名 (localhost) 而不是端口问题...
adress?不应该是address？
天哪！谢谢！

【解决方案1】：

将您的development.rb adress 配置更改为address。

这只是一个错字！ ;-)

从错误中可以看出，尝试的连接在正确的端口上，但在错误的主机上，所以问题是在主机名配置上搜索（至少，我是这样找到的）
