I set this to /Trash (seen as [Imap]/Trash within GMail), but the mail will always end up in [GMail]/Trash instead. Any other folder name won't work as well. This used to work fine with Thunderbird 2.0. Reproducible: Always Steps to Reproduce: 1. Account settings -> server settings -> When I delete a message: Set it to "Move it to this folder" and define any folder but [Gmail]/Trash. 2. Delete a message. Actual Results: Message ends up in [Gmail]/Trash instead of in the folder given above. Expected Results: Message should be located in the folder given above and NOT in [Gmail]/Trash.

It's current restriction of Tb to avoid unwanted problems around Gmail's particularity of "folder name is dynamically changed by Gmail according to Display Language: selection change by user" which is supported by Gmail's XLIST command use by Tb. You can perhapas see phenomenon of "icon of a folder you selected is changed to trash can icon, then is changed back to normal folder icon sooner or later" when you changed to "Move to this folder: other than [Gmail]/Trash". Tb probably internaly forces "trash==[Gmail]/Trash" just after internal setting of "trash==folder selected at trash folder selection UI". As Gmail's auto-expunging works on a mail to which \Deleted flag is stored unless you disable the Gmail's auto-expunging by advanced feature of Gmail's Lab, current recommendation is like next: (1) At Server Settings/Move to this folder:, select [Gmail]/Trash, in order to avoid your confusion. (2) Select IMAP delete model of "Remove it as immediately. As mail flagged \Deleted is automatically expunged by Gmail's auto-expunging, "Move to this folder" model is useless. Any mail flagged \Deleted at an IMAP folder(Gmail Label) is always kept in [Gmail]/All Mail. "Just mark it as deleted" model is useful for [Gmail]/Trash only. (3) If you really want to delete a mail(and original in [Gmail]/All Mail too), manually move the mail to [Gmail]/Trash. As original in [Gmail]/All Mail is moved to [Gmail]/Trash, copy in any IMAP folder(Gmail Lael) is also deleted. This is similar operation to "Delete at Gmail's Web Interface". (4) Mail in [Gmail]/Trash will be permanently removed after 30 days by Gmail. If you don't execute "Empty Trash" nor "delete at [Gmail]/Trash", and if within 30 days, you can do "Undo delete" like operation by "Move mail in [Gmail]/Trash to [Gmail]/All Mail. As seen in bug 620323, all Gmail Label is currently recovered by this "Undo delete" like move back operation. [Gmail]/All Mail.
