1. Introduction
In RFC 5965 [RFC5965], an Abuse Reporting Format (ARF) is defined for
reporting email abuse. Currently, two feedback report types are
defined that are related to the spam problem and that can be used to
report abusive or fraudulent email messages:
o abuse: indicates unsolicited email or some other kind of email
abuse.
o fraud: indicates some kind of fraud or phishing activity.
This specification defines a new feedback report type: "not-spam".
It can be used to report a message that was mistakenly marked as
spam.
1.1. Discussion
In some cases, the email client receives an email message that was
incorrectly tagged as spam, perhaps by the email system, or
accidentally by the user. The email client accepts the end user's
"not-spam" report instruction, retrieves information related to the
message, and reports this email as not-spam to the email operator.
When the email operator receives the report, it can determine what
action is appropriate for the particular message and user. (The
requirement for a not-spam report type is from the Open Mobile
Alliance (OMA) Spam Report Requirement Document [OMA-SpamRep-RD].)
For example, in response to a "not-spam" report, the email system can
remove the spam tag or otherwise reclassify the message, possibly
preventing similar email for this user from being marked as spam in
the future. The report can be used to adjust the training of an
automated classifier. After processing the report, the email

operator might send a notification to the email client about the
processing result (for example, by moving the message from one
mailbox to another, such as from "Junk" to "Inbox").
In most cases, "not-spam" reports will probably not be taken on their
own, but will be considered along with other information, analysis of
the message, etc. Because different users have different needs and
different views of what constitutes spam, reports from one user might
or might not be applicable to others. And because users might
