Question

我终于在开发时正确地发送了电子邮件确认（使用Devise进行身份验证等）但是在生产中我根本无法让它工作。

更新/编辑＃1：

在尝试下面的建议后，遗憾的是没有解决问题，然后我按如下方式修改了我的生产设置：

更新/编辑＃2：

试图修改:domain值：

  Rails.application.routes.default_url_options[:host] = 'obscure-crag-6843.herokuapp.com'

      config.action_mailer.raise_delivery_errors = true
      config.action_mailer.perform_deliveries = true
      config.action_mailer.delivery_method = :smtp
      config.action_mailer.default :charset => "utf-8"

      config.action_mailer.smtp_settings = {
        :address                  => 'smtp.sengrid.net',
        :port                     => 587,
        :authentication           => 'plain',
        :user_name                => ENV['SENDGRID_USERNAME'],
        :password                 => ENV['SENDGRID_PASSWORD'],
        :domain                   => 'obscure-crag-6843.heroku.com',
        :enable_starttls_auto     => true
      }
       # Enable locale fallbacks for I18n (makes lookups for any locale fall back to

      # the I18n.default_locale when a translation cannot be found).
      config.i18n.fallbacks = true

      # Send deprecation notices to registered listeners.
      config.active_support.deprecation = :notify

      # Use default logging formatter so that PID and timestamp are not suppressed.
      config.log_formatter = ::Logger::Formatter.new

      # Do not dump schema after migrations.
      config.active_record.dump_schema_after_migration = false

仍有错误：

此时我要么尝试使用其他邮件提供商，要么暂时回到Gmail，但当然我最终还是要处理这个问题。如果有人有任何更好的建议。

Answer 1

我认为这就是这条线：

    :address                  => 'smtp.sengrid.net',

Answer 2

我在生产（devise，heroku）中发送电子邮件时遇到了问题，但我能够解决它。将我的代码设置与您的代码设置进行比较，我发现这些代码不同：

Rails.application.routes.default_url_options [：host] ='obscure-crag-6843.herokuapp.com'

：domain =＆gt; 'obscure-crag-6843.heroku.com'，

：address =＆gt; 'smtp.sengrid.net'，

在

Rails.application.configure do

我有

config.action_mailer.default_url_options = {host：'myappname.herokuapp.com'}

并在

config.action_mailer.smtp_settings

除了

之外，一切都是一样的

：address =＆gt; 'smtp.sendgrid.net'，（你拼错了sendgrid）

：domain =＆gt; 'heroku.com'，

当然，您需要将Sendgrid添加到Heroku。希望这有帮助！

Answer 3

我注意到您在代码中使用了：domain属性。虽然我之前从未使用过，但您是否可以尝试将域名更改为app-name.heroku.com而不是heorku.com？我将向您展示我如何为自己使用邮件代码：

    config.action_mailer.perform_deliveries = true
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {
  address: "smtp.gmail.com",
  port: 587,
  authentication: "plain",
  enable_starttls_auto: true,
  user_name: ENV["gmail_username"],
  password: ENV["gmail_password"]
  }

祝你好运：）
