 Change log file for Exim from version 4.21

 PH/41 Added support for the use of login_cap features, on those BSD systems
       that have them, for controlling the resources used by pipe deliveries.
 
+PH/42 The content-scanning code uses fopen() to create files in which to put
+      message data. Previously it was not paying any attention to the mode of
+      the files. Exim runs with umask(0) because the rest of the code creates
+      files with open(), and sets the required mode explicitly. Thus, these
+      files were ending up world-writeable. This was not a big issue, because,
+      being within the spool directory, they were not world-accessible. I have
+      created a function called modefopen, which takes an additional mode
+      argument. It sets umask(777), creates the file, chmods it to the required
+      mode, then resets the umask. All the relevant calls to fopen() in the
+      content scanning code have been changed to use this function.
