GitLab 电子邮件通知未发送

我最近刚刚在 Ubuntu 12.04 服务器上安装了 GitLab v5.0，现在遇到了电子邮件通知问题。我无法让 GitLab 发送任何类型的电子邮件。

我有我的config/environments/production.rb使用 sendmail 作为传输服务的文件设置：

config.action_mailer.delivery_method = :sendmail
config.action_mailer.perform_deliveries = true
config.action_mailer.raise_delivery_errors = true

我可以从 shell 成功手动使用 sendmail，如下所述：http://scratching.psybermonkey.net/2011/03/sendmail-how-to-test-sending-email.html http://scratching.psybermonkey.net/2011/03/sendmail-how-to-test-sending-email.html

My config/gitlab.yml文件使用以下电子邮件设置进行设置：

email_from: [email protected] /cdn-cgi/l/email-protection

我读到这可能是 Sidekiq 未运行的问题，所以我运行了以下命令，但没有任何变化。我仍然无法发送电子邮件：

$ sudo -u git -H bundle exec rake sidekiq:start RAILS_ENV=production
$ ps aux |grep -i sidekiq
git       2791  2.1  4.2 206476 86620 pts/0    Sl   14:45   0:23 sidekiq 2.7.5 gitlab [0 of 25 busy] 

这向我表明 Sidekiq 确实正在运行...这里还有什么问题？不幸的是，GitLab 的 wiki 上似乎没有太多关于电子邮件设置的文档......

我发现 sidekiq.log 中记录了以下错误：

有任何想法吗？

这是我在 /config/environment/development.rb 最后的条目，这对我有用。

注释掉 sendmail 选项并使用外部 SMTP 中继

  ##config.action_mailer.delivery_method = :sendmail ## Comment out this
  # Defaults to:
  ## config.action_mailer.sendmail_settings = {
  ##   :location => '/usr/sbin/sendmail',
  ##   :arguments => '-i -t'
  ## }

  config.action_mailer.perform_deliveries = true
  config.action_mailer.raise_delivery_errors = true

  ## SMTP Settings
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {
      :address => '10.146.10.90', ## My SMTP Relay/Gateway
      :port => 25, ## SMTP Port
      :domain => 'gitlab.example.com', ## My Domain
      :authentication => :plain, ## Let it be plain as it is inside my LAN
      ##:user_name => '[email protected] /cdn-cgi/l/email-protection', ## This is not required as long as 
      ##:password => 'yourPassword', ## SMTP Gateway allows anonymous relay
      ##:enable_starttls_auto => true ## In LAN
      ##:user_name => '',
      ##:password => '',
      :enable_starttls_auto => true
  }
end
