    According to Laurent FACQ:
    
    > # mimeflood.pl - 02/08/1998 - L.Facq (facq@u-bordeaux.fr)
    
    This is generally a variant of the recently posted
    Sioux DoS attack and if you have applied the patch
    posted by Ben Laurie this 'mimeflood' script won't
    harm your server in any way.
    
    FYI, the next version of Apache will include the following new directives:
    
     - LimitRequestLine: limits the size of the request line
     - LimitRequestFields: limits the number of header lines
     - LimitRequestFieldsize: limits the size of each header line
     - LimitRequestBody: limits the size of the entity-body
    
    Sensible default values are used if the directives are unset
    which will prevent the server from beeing flooded with bogus requests...

    Redistributing private email is considered to be very rude... or do you
    have the permission from Roy to post his message?
