Abstract

Spamming has been a major PITA for any organization/person. Spammers have evolved with time and so the Anti-Spam engines. I’ll discuss about how spammers operate, various algorithms(Statistical, heuristic, reg exp) and protocols(SPF, DKIM, DNSxLs etc) used for Stopping Spam and how to evade those techniques. For Example: Evading Grey listing by resending a 4XX Error mail, Targeting a low priority MX host, testing your spam with freely available tools and free webmail services etc.
