+If non-nil, fetch the mail even when Gnus is unplugged. If you use
+directory source to get mail, you can specify it as in this example:
+
+@lisp
+(setq mail-sources
+ '((directory :path "/home/pavel/.Spool/"
+ :suffix ""
+ :plugged t)))
+@end lisp
+
+Gnus will then fetch your mail even when you are unplugged. This is
+useful when you use local mail and news.
