dovecot - Jan 2010 - STATUS command and total/read message count

Hello,

I'm running Dovecot 1.0.15 with Thunderbird 3.0.1. TB can query
folders for messages in two ways: Either by using the STATUS command,
or by opening the folder (don't know the respective IMAP commands,
sorry...).

Querying via opening the folder is reliable, but via the STATUS
command, only new/unread messages are shown. If I want to have the
total number of (unread) mesages in a folder, I have to manually open
it, so the headers are loaded. Is this a Dovecot issue, or a problem
with Thunderbird?

In other words: Does the STATUS command only return new/unread
messages, or can this be configured on the server side?

Thanks,
Florian

I don't understand. What's the difference between "new/unread"
and
"unread"? What does headers have to do with it?

There's no configuration. STATUS can only return number of messages,
messages without \Seen flag, number of messages with \Recent flag ("new
messages arrived since last time mailbox was selected"), and some other
less useful things.

the problem is the following: Thunderbird can show the number of
new/unread messages in a folder, as well as a total number of messages
in a folder. In Thunderbird 2.x, the latter worked with the infopane,
in Thunderbird 3.x, you have to use the Extra Folder Columns
extension.

When a new client is set up and launched for the first time,
Thunderbird queries all folders using the STATUS command, unless
mail.imap.use_status_for_biff is set to false.

Some folders have only read messages, others have only unread
messages, and some other have read and unread messages. Thunderbird
now only shows the number of unread messages in a folder when using
the STATUS command. In order to get the total number of messages in
one specific folder, I have to manually open it.

So, in short, Thunderbird doesn't seem to update the total number of
messages in a folder using the STATUS command.

Thunderbird problem - right? ;-)
