OpenTrashmail

OpenTrashmail is a self-hosted disposable email service that ships its own SMTP server. No database is required — all emails are stored as flat JSON files. It supports wildcard domains, RSS feeds, and a JSON API.

First-Time Setup

1. Click the deployed URL to open the OpenTrashmail web interface.
2. Enter any email address using your configured domain to view received emails.
3. Emails sent to any address at your domain will appear automatically.

Ports

• 80 (HTTP — Web interface)
• 25 (TCP — SMTP server for receiving emails)

Important Note

For full functionality, you need to configure DNS MX records pointing to your server so emails can be received on port 25. The web UI on port 80 displays received emails.
