Postfix + Sendmail（Rails）：邮件未发送

我有一个用于发送电子邮件的 rails 应用程序。它在我的其他 ubuntu 服务器上可以运行，但在这个服务器上不行。这是我在 /var/log 中的 mail.log：

我对 Postfix 以及配置它的方式不太熟悉。我可以telnet localhost 25毫无问题地进行配置。有人能帮我调试一下吗？

如果您需要更多信息，请告诉我。

我认为我之前曾看到过相同类型的消息（“SASL 客户端初始化：通用故障”），以下是对我有用的配置。造成差异的选项是 enable_starttls_auto 和 openssl_verify_mode。

这是config/configuration.ymlRedmine 安装文件。我不是 Rails 专家，不确定其他 Rails 应用程序的配置是否相同 - 可能只适用于那些使用 ActionMailer 发送邮件的应用程序。

您可以在 Rails 文档中找到更多信息：http://guides.rubyonrails.org/action_mailer_basics.html#action-mailer-configuration

但是我刚刚发现 openssl_verify_mode 选项没有记录，一些信息可以在这里找到：https://rails.lighthouseapp.com/projects/8994/tickets/6508-undocumented-actionmailer-openssl_verify_mode-option

# default configuration options for all environments
default:
  # Outgoing emails configuration (see examples above)
  email_delivery:
    delivery_method: :smtp
    smtp_settings:
      enable_starttls_auto: false
      openssl_verify_mode: 'none'
      address: your.mailserver.com
      port: 587
      domain: yoursenderdomain.com
      authentication: :login
      user_name: "username"
      password: "password"
