Problem Statement : Virus ....DOS(denail of services) ....spoofing ...hacking....routers....firewalls.

                   Further to as published in the document referred below viz. projects.pdf, as published or
                   envisaged elsewhere by this individual.

Opportunity :  Innovative extension to smtp or email routing or exchange between mx record holders in DNS

               ...by using concepts and extensions from certificate-servers,PGP ...etc

               ...spaming of mail-box's by un-known malware or non-traceable email-address's
 
               as also extraction of email-addresses / mailing-list by tweaking vulnerabilities 
 
               in smtp.

Note: The above problem statement having been encountered in various scenarios
      and detailed in various 'Proof of concepts' as mentioned in 
      'http://uk.geocities.com/ravivenkatus/projects.pdf' ....apply appropriate
      'use-case' modeling and arrive at a workable and feasible solution both
       commercially and techinically viable.
