"*Hook that will be run after the incoming mail has been transferred.
The incoming mail is moved from `nnmail-spool-file' (which normally is
something like \"/usr/spool/mail/$user\") to the user's home
-directory. This hook is called after the incoming mail box has been
+directory. This hook is called after the incoming mail box has been
emptied, and can be used to call any mail box programs you have
running (\"xwatch\", etc.)
Eg.
\(add-hook 'nnmail-read-incoming-hook
