Mozilla Mail 1.1 Release on Windows 2000 SP3 UW-IMAP 2001a on FreeBSD 4.6-STABLE 119 IMAP mail folders, including many like: Vendors/Software/McAfee Contract/Client/General How to replicate the bug: 1. Minimise all first level IMAP folders in the left pane of the Mail window. 2. Close Mozilla. 3. Start Mozilla. 4. Compose a new message. 5. Options/Send a copy to.../ try to pick any 3rd level IMAP folder Either the third level will not be visible in the menu (for example, no Client visible under Contract) or it will not be selectable (client visible under Contract, but it is greyed out and nothing appears under it). This will stay this way until the third level folders are opened in the left pane, then Mozilla is quit and restarted. If Mozilla is quit with the folders collapsed in the left pane, they will not be available for Filing and Copy to the next time it is started. This bug is 100% repeatable.

This picture demonstrates step 3 of the bug.
I've added three pictures to demonstrate the bug. The aim is to file the bug report into the IMAP folder ROTFL/PSB/Parking. Look at picture 1. Notice that the ROTFL folder is closed and has been closed since I started Mozilla. Click on the File icon, select the server and the ROTFL folder. Note that the PSB subfolder is greyed out, and cannot be used as a target for filing the message. Look at picture 2. I now expand the ROTFL folder in the folder list. You can see that there are three subfolders. Click on the File icon, select hte server and the ROTFL folder. The PSB subfolder is *still* greyed out. From this point on, it is impossible to file anything into folders into the PSB subfolder using the File icon. Look at picure 3. Quit Mozilla and restart it. Expand the ROTFL folder in the folder list *first*, before ever clicking on the File icon. You can now see the subfolders. Now use the File icon to successfully file items into the third level folder. This is completely repeatable behaviour and applies to *any* third level IMAP folder. It must be expanded the folder menu before trying to file to it. Note also that is necessary to manually expand any folder of level 3 or deeper, as Mozilla does not automatically detect them on launch.
Attached file IMAP trace of bug in action (deleted) —
This demonstrates how Mozilla handles IMAP. See the comments for why this is wrong.
Look at the IMAP trace attachment. This shows Mozilla using the following logic: 4 list "" "Mail/%" This is good to find the top level folders. It gives out things like: * LIST (\NoInferiors \UnMarked) "/" Mail/SAGE-AU * LIST (\NoSelect) "/" Mail/ROTFL * LIST (\NoSelect) "/" Mail/Vendors Which means that Mail/SAGE-AU is a normal folder that can take messages, and that Mail/ROTFL and Mail/Vendors aren't - which means they are folders that can only contain folders and not messages. Logically the next step is to recursively iterate down through the \NoSelect candidates looking for more folders. So I would have expected to see the next command being: 5 list "" "Mail/ROTFL/%" then 6 list "" "Mail/Vendors/%" But instead, what we get is this: 5 list "" "Mail/%/%" This is bad, as it just looks for level 2 folders. Some of these look like this: * LIST (\NoSelect) "/" Mail/ROTFL/ * LIST (\NoInferiors \UnMarked) "/" Mail/ROTFL/AMR * LIST (\NoInferiors \UnMarked) "/" Mail/ROTFL/GroPep * LIST (\NoInferiors \UnMarked) "/" Mail/ROTFL/IGC * LIST (\NoSelect) "/" Mail/ROTFL/PSB * LIST (\NoInferiors \UnMarked) "/" Mail/ROTFL/SupporterZone * LIST (\NoInferiors \UnMarked) "/" Mail/ROTFL/rotfl.com.au Which clearly shows that there are subfolders under the level 2 folders. However, Mozilla doesn't then look for level three folders with this: 6 list "" "Mail/%/%/%" It just stops. If I manually open the level 2 folder, Mozilla does this: 23 list "" "Mail/ROTFL/%" Which looks for the level 3 folders. So this exactly describes why the bug exists. Put simply Mozilla searches only for level 1 and 2 folders. It should iterate down looking for all folders. Phil.
if you use IMAP subscription, everything works fine. The option not to use subscription does not work well in Mozilla, unfortunately, since so few people don't use subscription. If you go into your imap server settings, click advanced, and only show subscribed folders, things should work a lot better. I agree this is a bug, but I'm just letting you know that if you can use subscription, things will work much better.

if we're not using subscription, we need to explicitly list non-verified folders
