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...

#Such limits have already been added to 1.3.2-dev.

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