Open Source standalone trashmail solution that ships its own mail server

Open Trashmail

Host your own trashmail solution to use with your own domains or subdomains

Features

• Python powered mail server that works out of the box for any domain you throw at it
• API for integrating it in your own projects. Can be used to give Users individual email adresses and read what they send to it
• Handles attachments
• Web interface to manage emails
• Generates random email adresses
• 100% file based, no database needed
• Can be used as Email Honeypot

Configuration

Just edit the config.ini You can use the following settings

• DOMAINS -> Comma separated list of domains this mailserver will be receiving emails on. It's just so the web interface can generate random addresses
• MAILPORT-> The port the Python powered SMTP server will listen on. Default 25
• ADMIN -> An email address (doesn't have to exist, just has to be valid) that will list all emails of all addresses the server has received. Kind of a catch-all
• DATEFORMAT -> How should timestamps be shown on the web interface (moment.js syntax)

Quick start

Simple start with no persistence

docker run -it -p 25:25 -p 80:80 hascheksolutions/opentrashmail

Saving data directory on host machine

docker run -p 80:80 -p 25:25 -v /path/on/host/where/to/save/data:/var/www/opentrashmail/data hascheksolutions/opentrashmail

Complete example with running as daemon, persistence, a domain for auto-generation of emails and auto restart

docker run -d --restart=always --name opentrashmail -e "DOMAINS=mydomain.eu" -e "DATEFORMAT='D.M.YYYY HH:mm'" -p 80:80 -p 25:25 -v /path/on/host/where/to/save/data:/var/www/opentrashmail/data hascheksolutions/opentrashmail

How it works

The heart of Open Trashmail is a python powered SMTP server that listens on incoming emails and stores them as json files. The server doesn't have to know the right Email domain, it will just catch everything it receives. You only have to expose port 25 to the web and set an MX record of your domain pointing to the IP adress of your machine.
