+        sudo sysctl -w kernel.unprivileged_userns_clone=1

+How to delete subfolder
+    /!\ IMAP folder needs to be empty
+    - remove mail from cur,new,tmp
+    - sync folder content
+    - remove ./cur/
+    - sync folder deletion
+
+Archive mail
+    mlist <maildir> | mpick -t 'date < "2017-01-01"' | mrefile 2016
