Node.JS Haraka SMTP Email Server (similar to PostFix)

REQUIRED: You will need to become familiar with: [login to view URL] (which is quite simple to learn - perhaps 1 hour max). PREFERRED: Docker I need an Email Forwarding Server (Haraka) where emails entering are mapped to another email that is in listed in a MONGODB AND MYSQL Database. eg. 1. Email enters server: abc[at][login to view URL] (where [login to view URL] is my domain name). 2. Haraka server looks in database to determine which email to forward to. i.e. abc[at][login to view URL] -> def[at][login to view URL] If no entry is found, it drops the message. 3. Haraka server relays the exact email to def[at][login to view URL] but may change some of the content such as From, Sender and Reply-To message header information. 4. It will also check if the incoming From/Sender is in a blocked list (which is stored in database) and will drop it. 5. It will also add a unique id tag to the email to prevent email forwarding loops. i.e. abc[at][login to view URL] forwards to def[at][login to view URL] which forwards to abc[at][login to view URL] 6. The Docker container should have HAProxy at the front to load-balance incoming data to different Haraka servers. (preferred) I am an experienced PHP/Golang/iOS developer but don't know Node.JS. I can help out with docker, HAProxy and MySQL/MongoDB advice. Haraka is very very simple to learn. It does 90% of all the requirements listed above - I just don't know Node.JS.
