Haraka Like: Simple to hook into the processing pipeline Dislike: Node.js and had some issues with stability when I last tried it. Source: over 1 year ago

For the record, I'm using dovecot (https://www.dovecot.org/) for IMAP and Haraka (https://haraka.github.io/) for SMTP. Source: about 2 years ago

Haraka (https://haraka.github.io/) is a plugin-based mailserver written in JavaScript. I've messed with postfix before but found Haraka easier because instead of arcane configuration files I can just read, copy, and tweak a plugin to suit my needs. Policies for receiving, storing, forwarding, and ignoring mail can be arbitrarily complex. Source: over 2 years ago

Exoprise leverages a node-based SMTP application, haraka, to process its messages as a well as series of custom plugins. You can read more about haraka here. Since its node-based its event driven, incredibly fast, and highly scable. Our auto-responders process 100’s of thousands of inbound and outbound messages each day, typically in < 10 milliseconds per each message. Source: over 2 years ago
