Status: RESOLVED DUPLICATE of bug 399475

(Thunderbird :: General, defect)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; pl; rv:1.9.0.6) Gecko/2009011913 Firefox/3.0.6 (.NET CLR 3.5.30729)

Shift + Delete doesn't delete a message permanently bypassing Trash folder when using IMAP protocol *although* default action on delete is to *move to Trash folder*, and not to *mark as deleted*. Instead a deleted message is marked as deleted and moved(archived) into *All* folder on Gmail server. It would make sense if the default action on delete would be *mark as deleted*, so the message would be moved directly to All folder and archived. 

Reproducible: Always

Steps to Reproduce:
1. Configure your Gmail account to use IMAP protocol.
2. Configure Thunderbird to receive email from Gmail account through IMAP protocol. Make sure that default action on delete is set to move to Trash folder which is a remote folder on Gmail server. 
3. Receive some emails. 
4. Delete email with Delete key. It will appear in Trash folder.
5. Delete other email from Received folder using Shift + Delete key combination.
6. Go to All folder (archive).
Actual Results:  
The email deleted with Shift + Delete key combination is marked as deleted instead of actually being permanently deleted.

Expected Results:  
The email deleted with Shift + Delete key combination should be permanently deleted and this should be synchronized with Gmail account through IMAP protocol  when default action on delete is to move to Trash folder. 

Tested this on Windows XP and Windows 7. On both operating systems I tried both Thunderbird 3 Beta 1 and Shredder nightly build Gecko/20090208 Shredder/3.0b2pre.

To [e-mail](bug opener):
Really DUP of Bug 399475?
I think your "is not permanently deleted" is "is not moved to [Gmail]/Trash", instead of "expunge is not issued", because "UID xxx store flag \Deleted" is equivalent to "UID xxx store flag \Deleted + EXPUNGE" when Gmail IMAP.
("[Gmail]/All Mail" is exception. If "[Gmail]/All Mail", Gmail will probably do nothing on Gmail Label when "flag \Deleted" is requested.)
Is it right?
