Title: Secdir review of draft-freed-sieve-in-xml-05 I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG.  These comments were written primarily for the benefit of the security area directors.  Document editors and WG chairs should treat these comments just like any other last call comments. This document describes a way to represent Sieve email filtering language scripts in XML.  Representing sieves in XML is intended not as an alternate storage format for Sieve but rather as a means to facilitate manipulation of scripts using XML tools. As such , this draft does not define a new protocol, but rather a way to wrap and handle an existing protocol. As this draft concludes, the security considerations of this draft equals reasonably to those of the Sieve protocol and those of using XML to represent information. Proper references to relevant security considerations seems to be present in this document and I can’t find any additional issues that I think the Security Area Directors should be aware of.
