You do not say what your MTA is but I have to assume postfix or sendmail (I
use exim) have some kind of mime type blocking as does exim so it's easy to
either reject or dev/null any email that has a .scr file attached (or any
other type for that matter) and it never get's to MailScanner or the user. I
dump about 1/2 dozen different file types that should never be sent (un
archived) including .src, right at the MTA level
