+/* Exim runs with umask(0) so that files created with open() have the mode that
+is specified in the open() call. However, there are some files, typically in
+the spool directory, that are created with fopen(). They end up world-writeable
+if no precautions are taken. Although the spool directory is not accessible to
+the world, this is an untidiness. So this is a wrapper function for fopen()
+that sorts out the mode of the created file.
+
+Arguments:
+ filename the file name
+ options the fopen() options
+ mode the required mode
+
+Returns: the fopened FILE or NULL
