我已设置 Discourse 2.7.12 并配置为通过 Mailgun 发送电子邮件。

尽管应用程序能够通过管理面板发送测试电子邮件，但所有相关的电子邮件作业在 Sidekiq 中都会失败。

有什么可能出错的吗？

## Sidekiq 错误示例：

Jobs::CriticalUserEmail  
{“type”=\>“forgot\_password”,  
“user\_id”=\>4,  
“email\_token”=\>“ca2fd58bd00511d21d04ca05da6239ad”, “current\_site\_id”=\>“default”  
}

Jobs::HandledExceptionWrapper: Wrapped ArgumentError: :arguments 应该是一个包含单独字符串参数的数组

## 堆栈跟踪信息

在 /logs 中，我可以看到一个标题为：

Job exception: :arguments 应该是一个包含单独字符串参数的数组

以及堆栈跟踪：

## 相关代码 (mail/network/delivery\_methods/sendmail.rb)

```plaintext
# Mail.defaults do
  # delivery_method :sendmail, :location => '/absolute/path/to/your/sendmail'
  # end
  #
  # Then just deliver the email as normal:
  #
  # Mail.deliver do
  # to 'mikel@test.lindsaar.net'
  # from 'ada@test.lindsaar.net'
  # subject 'testing sendmail'
  # body 'testing sendmail'
  # end
  #
  # Or by calling deliver on a Mail message
  #
  # mail = Mail.new do
  # to 'mikel@test.lindsaar.net'
  # from 'ada@test.lindsaar.net'
  # subject 'testing sendmail'
  # body 'testing sendmail'
  # end
  #
  # mail.deliver!
  class Sendmail
    DEFAULTS = {
      :location => '/usr/sbin/sendmail',
      :arguments => %w[-i]
    }

    attr_accessor :settings

    class DeliveryError < StandardError
    end

    def initialize(values)

      self.settings = self.class::DEFAULTS.merge(values)
      raise ArgumentError, ":arguments expected to be an Array of individual string args" if settings[:arguments].is_a?(String)
    end

```

是 initialize 方法引发了异常。

我通过将 SMTP 参数也设置为 Sidekiq 来修复了它

在 **/opt/bitnami/scripts/discourse-env.sh**  
中  
这些被导出

```plaintext
DISCOURSE_SMTP_HOST
DISCOURSE_SMTP_ADDRESS
DISCOURSE_SMTP_PORT_NUMBER
DISCOURSE_SMTP_USER
DISCOURSE_SMTP_USER_NAME
DISCOURSE_SMTP_PASSWORD

```

但是 Sidekiq 期望参数不带 DISCOURSE\_ 前缀。  
因此，添加以下内容解决了问题：

```plaintext
export SMTP_HOST=“xxx”
export SMTP_ADDRESS=“xx”
export SMTP_PORT_NUMBER=“587”
export SMTP_USER=“xxx”
export SMTP_USER_NAME=“xxx”
export SMTP_PASSWORD=“xxx”

```

我在发送测试电子邮件时遇到此错误。我尝试在 sidekiq 中添加 smtp 详细信息。注意：我已将其部署在 k8s 上。我使用的是 3.0.6 版本
