SMTP Stress Tool


This article discusses an SMTP stress tool to stress SMTP servers.

It supports a generated message with fixed size and workload folder. Workload folder must contain *.eml files that the stress tool starts sending to destination server. The stress tool also includes an embedded SMTP server for testing computer SMTP throughput.

There are some known limitations with XP SP2, it limits connection per second, so with small messages, the actual speed remains 60 msg/sec, and CPU usage is very low. It just won't utilize the CPU.
