AI Summary

HloolMail is a self-hosted email service that lets you create temporary or permanent email addresses on domains you control. It receives emails via SMTP, stores them, and provides both a web interface for reading messages and an API for programmatic access. The system supports custom domains, shareable inbox links, and webhook notifications. It's designed for developers who want to own their email infrastructure without relying on third-party temporary email services.

How It Works

1
💡 You discover you need a throwaway email

Maybe you're signing up for a service and don't want to give your real email address, or you're testing something that needs email verification.

2
🚀 You get your temporary inbox ready

You visit the service and it instantly gives you a random email address like 'curious-rabbit@temp-mail.example' that you can use right away.

3
✨ You paste the email where you need it

You copy your new email address and paste it into a signup form. The service receives the email on your behalf so you don't have to share your real address.

4
📬 You check your inbox for the message

Within seconds, you see the verification code or welcome email arrive. You read it directly in the web interface without any extra steps.

5
You might want to share or automate
👥
Share with friends

Generate a special link so others can view emails in your inbox without needing an account

🔌
Connect to your tools

Use a personal access key to fetch emails automatically from your own scripts or integrations

🎉 Email handled, privacy protected

You've verified your account or received your notification without exposing your real email. Everything works privately, and you can delete the temporary inbox whenever you're done.

What is HloolMail?

HloolMail is a self-hosted temporary email and custom-domain inbox platform built in Go. It solves the classic developer problem of needing throwaway email addresses for verification codes, testing, and automation without relying on third-party services. The platform runs as a single binary with both SMTP (port 2525) and HTTP API (port 3000), stores mail in PostgreSQL or SQLite, and deploys via Docker Compose. Users get a web console for management, a REST API for automation, and a CLI tool for scripting workflows like polling for incoming verification codes.

Why is it gaining traction?

The project targets developers who want the convenience of services like Temp Mail but running on their own infrastructure. The API-first design with API key authentication makes it trivial to integrate into CI/CD pipelines or automation scripts. The built-in CLI can poll for emails and extract verification codes with a single command, which is a practical touch for testing scenarios. Custom domain support with automated MX verification removes the friction of setting up domain-based inboxes, and the webhook system enables real-time notifications for incoming mail.

Who should use this?

Backend developers building services that need verified email addresses, QA engineers automating signup flows, or teams running self-hosted infrastructure who want email capabilities without spinning up a full Postfix setup. It's also useful for developers building products that need per-customer inbox isolation with custom domains. The project is less suited for teams needing high-volume production mail delivery or those without DevOps capacity to manage self-hosted services.

Verdict

HloolMail is a well-structured, feature-complete solution for self-hosted temporary email, but with a 0.800000011920929% credibility score and only 18 stars, it's early-stage software with limited community validation. The codebase shows thoughtful API design, good test coverage, and solid Go patterns, but production deployment requires careful evaluation of your operational capacity. Worth trying for personal or internal projects; for production use, monitor the project closely as it matures.
