Haraka is an open source[2]SMTP server. Its architecture is plugin-oriented[3] and event-driven. The server and its plugins are written in JavaScript[4] using the Node.js framework.[5]
Haraka follows a plugin model, implementing a very lightweight SMTP core and providing developers hooks into the mail flow.[6] Almost all of Haraka's functionality is built as plugins.
Haraka is frequently used as a filtering MTA in front of other MTAs that lack the performance and/or filtering capabilities of Haraka. Craigslist uses Haraka[9] to handle inbound and then forward validated connections to Postfix.[10] Bounce.io similarly uses Haraka to accept incoming messages and deliver them to their application engine. Mail Toaster 6 uses Haraka[11] similarly to accept incoming mail and forward to a qmail based message store.
