Rails 4 with Devise on Heroku - 发送邮件的问题
Rails 4 with Devise on Heroku - Issue with sending mail
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。
UPDATE/EDIT #1:
在尝试了下面的建议后不幸的是没有解决问题，然后我修改了我的生产设置如下：
UPDATE/EDIT #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。
我认为是这一行：
:address => 'smtp.sengrid.net',
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，但您可以尝试将域更改为您的 app-name.heroku.com 而不是 heorku.com 吗？我将向您展示我自己如何使用邮寄代码：
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:)
我在生产环境（devise、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 = { host: 'myappname.herokuapp.com' }
并在
config.action_mailer.smtp_settings
一切都一样，除了
:address => 'smtp.sendgrid.net', (you misspelled sendgrid)
:domain => 'heroku.com',
当然，您需要将 Sendgrid 添加到 Heroku。希望这对您有所帮助！
