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 addresses and read what they send to it
Handles attachments
Web interface to manage emails
Generates random email addresses
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 mail server 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)

Roadmap

Mail server
- Storing received mails in JSON
- Storing file attachments
Docker files and configs
Web interface
- Choose email
- Get random email address
- Download attachments safely
- Display Text/HTML
- API so all features from the site can also be automated and integrated
- Automatically check for new emails while on site
- Admin overview for all available email addresses
- Secure HTML, so no malicious things can be loaded
- Display embedded images inline using Content-ID
- Option to show raw email
- Delete messages
- Make better theme
Configurable settings
- Choose domains for random generation
- Choose if out-of-scope emails are discarded
- Automated cleanup of old mails
- Honeypot mode where all emails are also saved for a catchall account
- Optionally secure whole site with a password
- Optionally allow site to be seen only from specific IP Range

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, acceptng only emails for configured domains, cleanup for mails older than 90 days and auto restart

docker run -d --restart=unless-stopped --name opentrashmail -e "DOMAINS=mydomain.eu" -e "DATEFORMAT='D.M.YYYY HH:mm'" -e "DISCARD_UNKNOWN=false" -e "DELETE_OLDER_THAN_DAYS=90" -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 address of your machine.
