What is KumoMTA?
KumoMTA is the only true Open-Source PowerMTA alternative, capable of matching performance of several million messages per hour while providing granular traffic shaping configuration and automation across unlimited IPs.
KumoMTA is a more flexible PowerMTA alternative, offering a configuration and automation system powered by embedded Lua scripting, allowing it to be extended to accommodate any use case.
