exim4 - rejecting .com,.bat,.exe,.pif extensions

["BruceG" <bruce-lists@manygriffi.blogdns.net>]

Hey all,

      I had decided not to mess with my e-mail server, but not messing is a
short-term thing ;-)    I know exim4 has the ability to reject messages
based on the extension of file names in mime attachments. I haven't found
the file to change that in yet (the configuration is broken up into several
smaller files in different directories).

      Anyone have a pointer to what file/directory I need to hit to start
rejecting attachments that contain Windows executables?

Thanks, Bruce
