【问题描述】：

我正在开发一个使用 Mandrill 生成其电子邮件的 Rails 应用程序。我一辈子都无法让它在测试环境中工作！我希望能够使用 ActionMailer 方法来传递、阅读和解析电子邮件，但我不断收到：Errno::ECONNREFUSED: Connection refused - connect(2)

message.rb：

class Message < ActionMailer::Base
  require 'mandrill'
  default from: "My App <messages@myapp.com>"

  def send_welcome_email(to_user)
    mandrill = Mandrill::API.new ENV['MANDRILL_API_KEY']
    template = mandrill.templates.render "welcome-to-myapp", [], [
      {:name => 'username', :content => to_user.name},
      {:name => 'subject', :content => "Welcome to MyApp, #{to_user.name}"}
    ]
    @body = template['html']
    mail(:subject => "Welcome to MyApp, #{to_user.name}", :to => to_user.email, "tags" => ["In Trial - Welcome"],)
    headers['X-MC-Track'] = "opens"
    headers['X-MC-Tags'] ="invite_sent"
  end

end

production.rb

# Mailer configurations

  config.action_mailer.default_url_options = { :protocol => 'https', :host => 'app.myapp.com' }

  ActionMailer::Base.smtp_settings = {
    :address   => "smtp.mandrillapp.com",
    :port      => 25, # ports 587 and 2525 are also supported with STARTTLS
    :enable_starttls_auto => true, # detects and uses STARTTLS
    :user_name => ENV['MANDRILL_USERNAME'],
    :password  => ENV['MANDRILL_API_KEY'], # SMTP password is any valid API key
    :authentication => 'login', # Mandrill supports 'plain' or 'login'
    :domain => 'myapp.com', # your domain to identify your server when connecting
  }

test.rb

ActionMailer::Base.smtp_settings = {
   :address   => "smtp.mandrillapp.com",
   :port      => 25, # ports 587 and 2525 are also supported with STARTTLS
   :enable_starttls_auto => true, # detects and uses STARTTLS
   :user_name => ENV['MANDRILL_USERNAME'],
   :password  => ENV['MANDRILL_API_KEY_TEST'], # SMTP password is any valid API key
   :authentication => 'login', # Mandrill supports 'plain' or 'login'
   :domain => 'myapp.com', # your domain to identify your server when connecting
 }

 config.action_mailer.default_url_options = { :host => '192.168.11.44:3000' }
 config.action_mailer.delivery_method = :smtp

【问题讨论】：

您是否在 mandrill api 中添加了 ip 阻止？也许您将其修复到您的生产服务器并且来自其他 ip 的请求被阻止。

【解决方案1】：

检查您用来连接 mandrill 的端口。应该是 2525 或 587。

我认为这个问题和你的一样：Can't get Mandrill to send emails from Rails App。
