When I unsubscribe to a folder, the folder is deleted from the server!
This is very dangerous behaviour, as the folder is not recoverable (doesn't go in the Trash, it is deleted from the IMAP server). Here is some info about the environment:
Name Thunderbird Version 38.2.0 User Agent Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:38.0) Gecko/20100101 Thunderbird/38.2.0 Profile Folder Application Build ID 20150813074416 Enabled Plugins about:plugins Build Configuration about:buildconfig Memory Use about:memory

I've never seen anything like this reported against Thunderbird. So at first blush, this sounds like a bug in the server. Who is running the server?
