A proposal for an efficient way to prevent spam by analysing SMTP and HTTP tar pits towards their efficiency in fighting spam and combining them
Tobias Eggendorfer · International Conference on Communications · 2006
Unsolicited commercial email (UCE, spam) is the biggest threat to email communication. As of January 2005 more than 93% of all emails are spam. There are different attempts to fight spammers, one of those is to delay the collection of email addresses by setting up HTTP tar pits, another one is to delay the transmission of spam by setting up SMTP tar pits. This paper compares those two methods with a view to their efficiency in preventive spam fighting. It then analyses how SMTP and HTTP tar pits could be combined to increase their efficiency and provides results from a real world test.
