433134 - Sub-folders not shown in bold if new IMAP messages are filtered to them

Status: RESOLVED WORKSFORME

(Thunderbird :: Mail Window Front End, defect)

Description

[Scott Craig]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.4) Gecko/20070602 Firefox/2.0.0.4 (Swiftfox)
Build Identifier: version 2.0.0.0 (20070326)

This applies to my Windows XP PC, and to my Kubuntu Linux PC.

I use Thunderbird as an IMAP client to collect my messages from a sever. But I get so much mail that I set up filters to move the messages to subfolders.

When a new message comes in to my Inbox, the inbox icon gets a star and the text of "Inbox" and the new message details appear in bold as they should.

But messages that are filtered to the other folders do not cause the same behavior. It is only after I click on the sub-folder that the correct bold behavior occurs. Needless to say, this behavior renders the message filters worse than useless.

There seems to be some interaction with the power saving function of the PC. When Thunderbird is started or woken up, the sub-folders are not checked for new messages.

Reproducible: Always

Steps to Reproduce:
1. Configure Thunderbird to be an IMAP client.
2. Create a sub-folder under Inbox, and create a filter to redirect new messages there.
3. Send a message to yourself that meets the criteria of the filter. Quickly close Thunderbird.
4. Re-open Thunderbird. The sub-folder containing the new message will not appear in bold.
Actual Results:  
The message gets sent to the folder, but there is no indication that a new message is lying there. 

Expected Results:  
I expect the folder name to appear in bold with a star beside it.

The workaround for this problem is to not use filters at all. This doesn't seem like an "easy workaround" that would make this bug a minor one.

One might think that the problem arises with the interaction with the server. That is, the message is not actually downloaded yet. But I find that there could be hundreds of unread messages in there. That is far too many to instantly download the headers when the sub-folder is clicked. The messages must be already there.

Please enable mail.check_all_imap_folders_for_new = TRUE in config editor to check all folders. Report back if it works for you.

Thank you for the suggestion. This seems to have fixed it. I installed the Thunderbird add-on "AboutConfig" to make the modification.

btw
There no need for additional addons, config editor lies here Tools->Options->Advanced->Config Editor

Thanks for the tip, but I'm using Thunderbird 2.0 on Ubuntu. So I see the config editor lies under Edit>Preferences>Advanced>Config Editor. I didn't find it before. (There is no "options" choice on the Tools menu.)

You can also set individual folders to be checked through the folder context menu.
