BOUNCE事件类型定义

基于Postfix BOUNCE守护进程的实际功能开发 BOUNCE守护进程负责：

  • 生成投递失败通知邮件
  • 生成发送者和邮件管理员通知
  • 处理格式错误请求
  • 管理退信和延迟通知的生成

Variants§

§

SenderNotification

发送者投递失败通知事件

当邮件投递失败时，BOUNCE守护进程为原始发送者生成一个投递失败通知邮件 这是BOUNCE组件最主要的功能，占95%+的日志量

示例日志： “5FC392A20996: sender non-delivery notification: 732B92A209A3”

Fields

§base: BaseEvent

基础事件信息

§original_queue_id: String

原始邮件的队列ID

§bounce_queue_id: String

生成的退信通知邮件的队列ID

§

PostmasterNotification

邮件管理员投递失败通知事件

当邮件投递失败且需要通知邮件管理员时生成 通常在复杂的投递失败场景中出现

示例日志： “633F488423: postmaster non-delivery notification: 6DFA788422”

Fields

§base: BaseEvent

基础事件信息

§original_queue_id: String

原始邮件的队列ID

§bounce_queue_id: String

生成的管理员通知邮件的队列ID

§

Warning

BOUNCE守护进程警告事件

处理BOUNCE服务过程中出现的各种警告 包括格式错误、配置问题、资源限制等

示例日志： “warning: malformed request”

Fields

§base: BaseEvent

基础事件信息

§warning_type: BounceWarningType

警告类型

§details: String

警告详细信息
