Haraka

Extensible Node.js SMTP server

About Haraka

Haraka is an SMTP server written in Node.js known for speed and a plugin system covering spam filtering and delivery logic. It runs on your own server or home hardware, so your data stays under your control instead of depending on a third-party cloud service. For teams, the appeal is control: audit the code, extend it where the license allows, and keep the workflow running even if a vendor changes direction.
