Recent discussions have shown that it is desirable to set different [IMAP] flags on message delivery. This can be done, for example, by a Sieve interpreter that works as a part of a Mail Delivery Agent. This document describes an extension to the Sieve mail filtering language for setting [IMAP] flags. The extension allows to set both [IMAP] system flags and [IMAP] keywords.
