A New Internet-Draft is available from the on-line Internet-Drafts directories.
Abstract: ‘This document defines a new keyword parameter, “:copy”, to be used with the sieve “fileinto” and “redirect” actions. The new parameter prevents cancellation of the implicit keep.’
Changes from the previous version: ‘added IANA considerations, inserted Appendix B (Intellectual Property Rights Statement), changed Appendix A “References” to “Normative References” and added brief example.’
