From 3648b4d996be3e89d53a9beefc448c7129e3a49f Mon Sep 17 00:00:00 2001 From: Michael Haggerty Date: Tue, 15 Jan 2013 09:06:27 +0100 Subject: imap-send.c: remove namespace fields from struct imap They are unused, and their removal means that a bunch of list-related infrastructure can be disposed of. It might be that the "NAMESPACE" response that is now skipped over in get_cmd_result() should never be sent by the server. But somebody would have to check the IMAP protocol and how we interact with the server to be sure. So for now I am leaving that branch of the "if" statement there.
