Internet-Draft ARF Source Ports April 2012
1. Introduction
[ARF] defined the Abuse Reporting Format, a new header message format
for use in reporting incidents of email abuse. It was extended by
[AUTHFAILURE-REPORT] to enable reporting of email authentication
failures. Although those specifications gave the capability to
include the source IP address in the report, the source port was not
included. As explained in [LOG], the deployment of IP sharing
techniques means it can now be essential to include source port
values in reports if unambiguous identification of the origin of
abuse is to be achieved.
Accordingly, this memo registers an ARF reporting field to contain
this information and provides guidance for its use.
2. Keywords
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].
3. Source-Port Field Definition
A new ARF reporting field called "Source-Port" is defined. When
present in a report, it MUST contain the TCP or UDP source port
matching the "Source-IP" field in the same report, thereby describing
completely the origin of the abuse incident.
Per, [ABNF], the formal syntax is:
source-port = "Source-Port:" [CFWS] 1*DIGIT [CFWS] CRLF
"CFWS" is imported from [MAIL].
When any report is generated that includes the "Source-IP" reporting
field, this field SHOULD also be present.
4. IANA Considerations
IANA is requested to add the following entry to the Feedback Report
Header Fields registry:
Field Name: Source-Port
Description: TCP or UDP source port from which the reported
connection originated

5. Security Considerations
