I now understand this after reading through the maildir++ specification. This leads me to make two suggestions. If possible it would be great if the documentation that is shipped with binc specifically spells out that if you plan on having Mozilla Thunderbird as a supported client then you better change your bincimap.conf file from Maildir++ to IMAPdir.If anything, I think that the documentation shipped with Binc should point specifically to http://lifewithbincimap.org/index.php/Main/IMAPClientsWithBinc when discussing IMAP clients. I don't think that the Andy should be responsible for maintaining accurate information for all IMAP clients. That task is better done by the user community, particularly the ones that are using a particular IMAP client in a production environment.
Second, I suggest this page (http://www.bincimap.org/bincimap-imapdir.html)specifically mention that root level directories are not allowed formaildir++ mail depots.Maybe, but maybe not... since this might be irrelavent to the end user (see below) and since Maildir++ is somebody else's creation (see http://www.inter7.com/courierimap/README.maildirquota.html)
Well I don't think Thunderbird can be configured this way. Since reading your mail I discovered http://lifewithbincimap.org/index.php/
Main/ThunderbirdFolderSetup. Within that document Jeremy explains how to configure the "Sent", "Drafts", and "Template" folders, but I don't see anything there or in the Thunderbird configuration that allows the configuration of the Trash folder. Google doesn't yield a solution either. The only possible work around that I see is to use an extension that bypasses the Trash folder all together. Such an extension can be found at: http://forums.mozillazine.org/viewtopic.php?t=56397.
So would you consider this a bug of Thunderbird? The situation is that Thunderbird insists on having a root level Trash folder. If the folder doesn't exist or can't be created then nothing can be deleted. Kind of a problem if you want to keep your email depot at a decent size.
Besides using IMAPdir, there two ways to address this in Thunderbird:
1. In "Account Settings", in "Server Settings" click the "Advanced button".
On the "IMAP" tab set the "IMAP Sever Directory" to "INBOX/". Now,
Thunderbird has no problems creating the "Trash" folder and all the
other folders appear as siblings of "INBOX".
1. In "Account Settings", in "Server Settings", set the "When I delete a
message" to "Remove it immediately"; if this is too drastic, then
change the setting to "Mark it as deleted" and the trashed emails will
be permanently deleted the next time you command Thunderbird to do so.
Note that I am only using Thunderbird 0.4 in my lab, but I don't think that these things have changed since.
