This paper shows that the performance of the generic SMTP servers are more limited than one previously thought. The paper implemented an environment to test SMTP server performance focusing on Denial of Service (DoS) attacks. The measurements show that a standard SMTP server can be easily overloaded by sending simple email messages and the overload can occur without consuming all network bandwidth. The measurements also show that the usage of content filtering applications can harm the performance so much that the server become even more vulnerable to DoS attacks. The paper describes the problems of performance measurements in SMTP environment and also gives a detailed background about the performed measurements.
