+# In between synchronisations, OfflineIMAP can monitor mailboxes for new
+# messages using the IDLE command. If you want to enable this, specify here
+# the folders you wish to monitor. Note that the IMAP protocol requires a
+# separate connection for each folder monitored in this way, so setting
+# this option will force settings for:
+# maxconnections - to be at least the number of folders you give
+# holdconnectionopen - to be true
+# keepalive - to be 29 minutes unless you specify otherwise
+# This option should return a Python list. For example
+#
+# idlefolders = ['INBOX', 'INBOX.Alerts']
+#
