[ARF] defined the Abuse Reporting Format, an extensible message format for Email Feedback Reports. These reports are used to report incidents of email abuse. ARF was extended by [AUTHFAILURE-REPORT] to enable the reporting of email authentication failures. These specifications provided for the source IP address to be included in a report. As explained in [LOG], the deployment of IP address sharing techniques requires the source port values to be included in reports if unambiguous identification of the origin of abuse is to be achieved.
[ARF]定义了滥用报告格式，这是一种用于电子邮件反馈报告的可扩展消息格式。这些报告用于报告电子邮件滥用事件。ARF由[AUTHFAILURE-REPORT]扩展，以允许报告电子邮件身份验证失败。这些规范提供了要包含在报告中的源IP地址。如[LOG]中所述，如果要明确识别滥用来源，IP地址共享技术的部署要求在报告中包含源端口值。
This document defines an ARF reporting field to contain this information and provides guidance for its use.
本文件定义了包含此信息的ARF报告字段，并为其使用提供了指导。
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [KEYWORDS].
本文件中的关键词“必须”、“不得”、“必需”、“应”、“不应”、“应”、“不应”、“建议”、“可”和“可选”应按照[关键词]中所述进行解释。
A new ARF header field called "Source-Port" is defined. When present in a report, it MUST contain the client port of the TCP connection from which the reported message originated, corresponding to the "Source-IP" field that contains the client address of that same connection, thereby describing completely the origin of the abuse incident.
定义了一个称为“源端口”的新ARF头字段。当在报告中出现时，它必须包含报告消息来源的TCP连接的客户端端口，对应于包含同一连接的客户端地址的“源IP”字段，从而完全描述滥用事件的来源。
Per, [ABNF], the formal syntax is:
根据[ABNF]，形式语法为：
source-port = "Source-Port:" [CFWS] 1*5DIGIT [CFWS] CRLF
source-port = "Source-Port:" [CFWS] 1*5DIGIT [CFWS] CRLF
"CFWS", which represents email-style comments or folding white space, is imported from [MAIL].
“CFWS”表示电子邮件样式的注释或折叠空白，从[MAIL]导入。
When any report is generated that includes the "Source-IP" field (see Section 3.2 of [ARF]), this field SHOULD also be present, unless the port number is unavailable.
生成包含“源IP”字段的任何报告时（参见[ARF]第3.2节），该字段也应存在，除非端口号不可用。
Use of this field is RECOMMENDED for reports generated per [AUTHFAILURE-REPORT] (see Section 3.1 of that document).
建议根据[AUTHFAILURE-REPORT]生成的报告使用此字段（参见该文档的第3.1节）。
[LOG] underscores the importance of accurate clocks when generating reports that include source port information because of the fact that source ports can be recycled very quickly in Internet Service Provider environments. The same considerations described there apply here.
[LOG]强调了在生成包含源端口信息的报告时精确时钟的重要性，因为在Internet服务提供商环境中，源端口可以很快回收。此处所述的注意事项同样适用。
Report generators that include an Arrival-Date report field MAY choose to express the value of that date in Universal Coordinated Time (UTC) to enable simpler correlation with local records at sites that are following the provisions of [LOG].
包含到达日期报告字段的报告生成器可以选择以世界协调时间（UTC）表示该日期的值，以便与遵守[LOG]规定的现场的本地记录进行更简单的关联。
IANA has added the following entry to the "Feedback Report Header Fields" registry:
IANA已将以下条目添加到“反馈报告标题字段”注册表中：
Field Name: Source-Port
字段名称：源端口
Description: TCP source port from which the original message was received
描述：从中接收原始消息的TCP源端口
Multiple Appearances: No
多次出现：否
Related "Feedback-Type": any
相关“反馈类型”：任何
Reference: [RFC6692]

Status: current

This extension introduces no new security considerations not already covered in [ARF].
此扩展没有引入[ARF]中尚未涉及的新安全注意事项。
Some security considerations related to the general topic of source port logging can be found in [LOG].
与源端口日志记录的一般主题相关的一些安全注意事项可以在[LOG]中找到。
