【问题描述】：

我终于在开发中正确发送了电子邮件确认（使用 Devise 进行身份验证等），但在生产中我根本无法让它工作。

更新/编辑#1：

在尝试了以下建议但不幸的是没有解决问题后，我修改了我的生产设置如下：

更新/编辑#2：

尝试修改: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

仍然出现错误：

在这一点上，我要么尝试使用不同的邮件提供商，要么暂时回到 Gmail，当然我最终将不得不处理这个问题。如果有人有更多的建议，那就太好了。

【解决方案1】：

我在生产（设计、heroku）中发送电子邮件时也遇到了问题，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，我发现这些行不同：

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

:domain => 'obscure-crag-6843.heroku.com',

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

在

Rails.application.configure do

我有

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

在

config.action_mailer.smtp_settings

一切都一样，除了

:address => 'smtp.sendgrid.net',（你拼错了 sendgrid）

:domain => 'heroku.com',

您当然需要将 Sendgrid 添加到 Heroku。希望这会有所帮助！

顺便谢谢你。 :)

【解决方案2】：

我认为是这一行：

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

【讨论】：

【解决方案3】：

我注意到您在代码中使用了 :domain 属性。虽然我以前从未使用过，但您能否尝试将域更改为您的 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:)

谢谢你，这并没有解决它，但我会继续努力:)
