From 69ed15343f169ea62085845cc36d3775d9452407 Mon Sep 17 00:00:00 2001
From: Art Cancro <ajc@citadel.org>
Date: Wed, 13 Jun 2007 02:46:31 +0000
Subject: [PATCH] Checked in a skeleton of the IMAP METADATA extension
 (draft-daboo-imap-annotatemore-11).  This will not be a full implementation
 of the extension.  We are only going to implement enough of it to handle
 folder types in the Outlook connector.
