Haraka MongoDB Plugin

A plugin for the Haraka SMTP server that stores incoming and outgoing emails in MongoDB, with attachments saved to disk. Current stable version is 1.8.6, actively maintained by Helpmonks, supporting high throughput (500k+ emails/day). Key differentiators: built-in attachment content type/name filtering, inline image conversion (to base64 or path), connection string support, and optional attachment path health checks. Compatible with mailparser and tnef for winmail.dat handling.
