ruby-on-rails - 如何配置通过本地应用服务器发送电子邮件而无需身份验证？

Question

我已经在config/initializers/下配置了Rails邮件程序，如下所示:

/config/initializers/setup_email.rb

config.action_mailer.raise_delivery_errors = true

  ActionMailer::Base.smtp_settings = {
   :address => "smtp.gmail.com",
   :port => 587,
   :domain => 'gmail.com',
   :authentication => :plain,
   :user_name=><username>,
   :password=><password>,
   :enable_starttls_auto => true
}

它工作正常，我可以发送电子邮件并接收它们。

但是，如何配置它以不通过身份验证(没有用户名和密码)从本地主机发送电子邮件，那不是使用gmail，而是通过应用程序的本地服务器发送电子邮件，那么该如何配置？

当使用localhost时，我得到的错误消息是:

如果您已经设置了本地SMTP服务器，则应仅提供以下连接详细信息:

config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
    :address              => "localhost",
    :port                 => 25
}

您应该在config/environments/*。rb文件中包含该文件。
