feature request: maintain folder structure with expunged email

[Marc]

Currently when I am expunging messages, the expunged (to be purged messages) are counted / listed at INBOX.

Say for instance that a user would accidentally delete the mailbox 2014. The whole folder structure below it would be lost. If someone creates a folder structure, this folder structure has important added value.

I have my doubts on this design discarding of mailboxes like this. I think the use of mailboxes/folder structures is not valued enough. If you have a lot of email and put these emails in folders, the folder structure is part of the important information. Currently this 'important information' is lost with expunging. 

I can understand that it maybe quite an effort to implement preserving this information. But using the doveadm import to restore a lot of emails, is really not an option. 
I assume that also restoring email from a specific folder does not work. Say I delete foldera, folderb and folderc. How can I get back folderb.
