+  - get_envelopes_list()
+
+  * we advise you to implement these functions :
+
+  - select_folder() (in case a session can access several folders)
+  - noop() (to check if the server is responding)
+  - check_folder() (to make a checkpoint of the session)
+  - status_folder(), messages_number(), recent_number(), unseen_number()
+      (to get stat of the folder)
+  - append_message() (but can't be done in the case of POP3 at least)
+  - login() in a case of an authenticated driver.
+  - starttls() in a case of a stream driver, if the procotol supports
+      STARTTLS.
+  - get_message_by_uid() so that the application can remember the message
+      by UID and build its own list of messages.
