Maildrop - Temporary Email Under Your Control

Sound familiar? Need to sign up for a sketchy website but don't want to expose your primary email? Or need to create multiple accounts for testing but email services block bulk registrations? There's a solution – Maildrop, a self-hostable temporary email service.

What's in the box?

Maildrop is a lightweight application that:

• Generates random email addresses on your domain
• Receives incoming emails without setting up a full mail server
• Automatically cleans up old emails
• Allows protecting important mailboxes with a password

The main advantage over public services like Temp-Mail is complete control over your data and no restrictions on the number of addresses.

Key features

1. Flexible address generation

   • Random addresses like [email protected]
   • Ability to set custom aliases
   • Password protection support for individual mailboxes

2. Simple interface

   • Minimalist web interface without clutter
   • View emails directly in the browser
   • Automatic email list refresh

3. Ready to use in 5 minutes

   • Launch via Docker or native Python script
   • Detailed DNS configuration guide
   • Flexible configuration parameters via .env file

How does it work technically?

Under the hood, Maildrop uses:

• Flask for the web interface
• Built-in SMTP server for receiving mail
• Simple file-based storage for emails (can be replaced with a database)

The architecture is intentionally kept as simple as possible – it's not a full mail server, but specifically a tool for temporary addresses.

Use cases

1. Safe sandbox Testing new services? Create a unique address for each test – no spam in your main inbox.

2. Development and debugging Need to test email newsletter functionality? Maildrop lets you instantly create dozens of test addresses.

3. Anonymous registrations For forums, temporary accounts, and services where you don't want to expose your primary email.

Setup in 3 steps

1. Deploy the server (Docker image or directly via Python)
2. Configure DNS records (MX and A records)
3. Open port 25 (or use cloud hosting)

Example docker-compose config:

services:
  maildrop:
    image: haileyydev/maildrop:latest
    ports:
      - "5000:5000"
      - "25:25"
    environment:
      - DOMAIN=yourdomain.com

Pros and cons

✅ Full control over temporary email ✅ Simple deployment ✅ Open source (GPLv3)

❌ Requires your own domain ❌ No email encryption ❌ Basic functionality (no search, filters)

Who will find it especially useful?

• Developers testing email functionality
• Power users who care about privacy
• Admins who need a simple way to create many test accounts

Try Maildrop – it might be exactly the tool you've been missing for working with temporary email. And if you find the features lacking, the project is open for improvements – the source code awaits your pull requests!
