I can't say what you are missing, as I don't know what you have. :-)

As an example, I provide a piece of my configuration. I have a list of
"bad" filename extensions in a file called /etc/exim/blacklist_files
which contains extensions to block (one perl line):

    bat
    chm
    cmd
    ...


Here's exim.conf stuff:

# main
BLACKLIST_FILES = /etc/exim/blacklist_files
FILENAME_EXT = ${sg{$mime_filename}{^.+\\.([a-z0-9]+)\$}{\$1}}

acl_smtp_mime = acl_check_mime

# ACL
acl_check_mime:
    deny
        message = File type blacklisted (filename: $mime_filename)
        condition = ${lookup{FILENAME_EXT}lsearch{BLACKLIST_FILES}{yes}{no}}


    accept


G'luck.
