Appendix A. Acknowledgments

This work began in 2004 and has evolved through numerous rounds of community review; it derives from a section in an early version of [RFC5068]. Over its 5 years of development, the document has gone through 14 incremental versions, with vigorous community review that produced many substantive changes. Review was performed in the IETF and other email technical venues. Although not a formal activity of the IETF, issues with the document's contents were resolved using the classic style of IETF community open, group decision-making. The document is already cited in other work, such as in IMAP and Sieve specifications and in academic classwork. The step of standardizing is useful to provide a solid and stable reference to the Internet's now-complex email service.

Details of the Originator Actor role was greatly clarified during discussions in the IETF's Marid working group.

Graham Klyne, Pete Resnick, and Steve Atkins provided thoughtful insight on the framework and details of the original drafts, as did Chris Newman for the final versions, while also serving as cognizant Area Director for the document. Tony Hansen served as document shepherd through the IETF process.

Later reviews and suggestions were provided by Eric Allman, Nathaniel Borenstein, Ed Bradford, Cyrus Daboo, Frank Ellermann, Tony Finch, Ned Freed, Eric Hall, Willemien Hoogendoorn, Brad Knowles, John Leslie, Bruce Valdis Kletnieks, Mark E.

Samik-Ibrahim, Marshall Rose, Hector Santos, Jochen Topf, Greg Vaudreuil, Patrick Cain, Paul Hoffman, Vijay Gurbani, and Hans Lachman.

Diligent early proof-reading was performed by Bruce Lilly. Diligent professional technical editing was provided by Susan Hunziker.

The final stages of development for this document were guided by a design team comprising Alexey Melnikov, Pete Resnick, Carl S. Gutekunst, Jeff Macdonald, Randall Gellens, Tony Hansen, and Tony Finch. Pete Resnick developed the final version of the section on internationalization.
