The IESG has approved the following document: - 'Sieve: An Email Filtering Language ' <draft-ietf-sieve-3028bis-13.txt> as a Proposed Standard This document is the product of the Sieve Mail Filtering Language Working Group. The IESG contact persons are Lisa Dusseault and Chris Newman. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-sieve-3028bis-13.txt Technical Summary This document describes a language for filtering email messages at time of or after final delivery. It is designed to be implementable on either a mail client or mail server. It is meant to be extensible, simple, and independent of access protocol, mail architecture, and operating system. It is suitable for running on a mail server where users may not be allowed to execute arbitrary programs, such as on black box Internet Message Access Protocol (IMAP) servers, as it has no ability to shell out to external programs. This document is a revision of RFC 3028. Process and goals history of this draft. This document is a revision of RFC 3028. In addition to updating boilerplate, updating and splitting references into normative and informative, and correcting ABNF errors, the document also clarified many ambiguities in RFC 3028, such as handling of invalid RFC 2047 encoding, invalid addresses in headers, invalid header field names in tests, unknown envelope parts, null return-path in "envelope" test, capability string case-sensitivity, etc. This update also brings Sieve in line with the recent comparator RFC 4790) and removes some requirements which were found to be problematic when designing some Sieve extensions, for example the ban on tests having side-effects was removed due to introduction of Sieve variables. Note that description of the reject action originally specified in RFC 3028 was moved to another draft. The first WGLC on the draft has ended at the beginning of August 2005. After the LC WG members realized that the document was unclear on how it was using comparators. Most of the time in the following year was spent on building common understanding on how comparators should work in general and how they are to be used in Sieve. Also, during this period some additional issues were clarified in the document. Now that RFC 4790 is published, the update to RFC 3028 can be sent to IESG. This draft is being submitted for Proposed Standard. The SIEVE WG has reviewed the draft and discussed it at a several meetings. Last-call (and post last-call) reviews included: - Kjetil Torgrim Homme - Ned Freed - Michael Haardt - Ken Murchison - Mark E.
