As Chair of the IETF, I wish to draw the Commission's attention to the Internet Engineering Task Force's decision to create a Proposed Standard for message labelling, as described in "A No Soliciting SMTP Service Extension" (draft-malamud-no-soliciting-07). This document describes a labelling mechanism for messages that does not use up valuable space in a subject line, allows for globally unambigous labelling indicating the purpose of a message, and does not require the creation of any new centralized registries. I believe that this standard can be used to make the provisions of the CAN-SPAM act more effective in allowing consumers to distinguish between desired and undesired communication, and is superior to the use of subject-line markers only.
