Drag & drop msg into new subfolder (IMAP) fails

When using IMAP it seems I am not able to drag the message into the new

This is actually Mac OSX 10.10.1 (Yosemite)
I have just looked at the folder creation code and at the moment it doesn't
really "wait" for the new folder to be created. it only executes a loop which
isn't asynchronous (so that Thunderbird doesn't really get time to synchronize
with the IMAP server); so the chances are that I can fix this by pushing the
"Move mail" code to a function and with a setTimeout that retries if the folder
isn't there / ready.
Great news, Axel. I was suspecting that it was just a "wait loop" by its
behavior. I couldn't imagine that it would natively discriminate pop versus

Test version with the asynchronous method. There is quite a bit different here
as I also noticed there are obsolete popup menus generated on dragging mails
onto the Tabs so I dealt with them. There was also a bug that the very first
drag onto a tab did not bring up a popup menu, so I fixed that one as well.
However on my test account "firstname.lastname@example.org" I keep getting "Too
many simultaneous connections" after generating new folders. Starting to think
that there is some serious restriction on the number of folders that can be
synchronized using IMAP. Which would be bad news as my (mostly POP) mail
accounts have several hundred.
Alsom I could actually not reproduce the "actual problem" of the server not
actually generating the folder, so the actual "move messages" code was actually
always executed the "first time round". YMMV :)
Please have a try with this one. For testing I highly recommend enabling the
debug option "extensions.quickfolders.debug.dragToNew" and debug mode

I have another user who consistently has the same behavior on an IMAP server:
the message in his case seemed to move, but then "bounced back" into the Inbox.
I am considering 2 things
- putting in a configurable delay in the move message for this case. This can
be done relatively easily but it is an imperfect solution as the required delay
might not just vary by server but also depend on current network load etc.
- somehow finding out whether the folder is already synchronized with the mail
server. This would be superior but I am not sure whether it is possible. I will
try to get some info on this on the #maildev developer group on Mozilla's IRC.

The [x] debug checkbox switches on the debug mode (by putting
extensions.quickfolders.debug = true) - which means QuickFolders will become
other switches you enable by right-clicking will selectively add more text, it
is not recommended to switch on *everything*; there are usually specific
settings which help debugging specific functionality. Otherwise you will just
"flood" the console with too many message and it becomes less helpful.
I will likely add some more output to the specific

I know this took a long time, but eventually had to get there. I am using an
asynchronous task for this, so it will only work on recent Thunderbird builds
To test this, go to QuickFolders Options > Advanced
Menu Configuration / Mail COmmands
Enable [x] Drag to new Subfolder
Right-click the option
extensions.quickfolders.dragToCreateFolder.imap = true
drag an email to and (IMAP) QuickFolder Tab and on to the "New folder..."
