Abstract
Most unsolicited commercial email (UCE) countermeasures call for a message by message analysis. However, some UCE attacks occur when a single sender of UCE floods a mail transfer agent (MTA) with a number of copies of a UCE, in a mail flood attack. The attacks rarely rise to the level of denial of service attacks but are significant enough to place a strain on MTAs and anti-UCE countermeasures. The anti-mail flood methodology disclosed herein provides a system and method for protecting mail systems from such mail flood attacks enabling anti-UCE countermeasures to work more efficiently.
