Policy-Mandated Labels Such as "Adv:" in Email Subject Headers Considered Ineffective At Best

Overview

RFC 4096, “Policy-Mandated Labels Such as "Adv:" in Email Subject Headers Considered Ineffective At Best”, is an Informational document published in May 2005 by C. Malamud. The canonical text is published by the RFC Editor.

Abstract

This memo discusses policies that require certain labels to be inserted in the "Subject:" header of a mail message. Such policies are difficult to specify accurately while remaining compliant with key RFCs and are likely to be ineffective at best. This memo discusses an alternate, \%standards-compliant approach that is significantly simpler to specify and is somewhat less likely to be ineffective. This memo provides information for the Internet community.
