Learn how to build your own disposable email service that lets you:

• Create instant email addresses
• Receive emails programmatically
• Protect your primary email from spam
• Manage multiple temporary addresses

What You'll Need

1. A Hostinger hosting plan (Premium recommended)
2. A registered domain (e.g., yourdomain.com)
3. Basic Python knowledge

Step 1: Set Up Catch-All Email on Hostinger

Configure your domain to receive all emails:

1. Log in to Hostinger control panel

2. Navigate to Emails → Email Accounts

3. Create main account (e.g., catchall@yourdomain.com)

4. Go to Forwarders → Create Catch-All

5. Select your main email as recipient

Step 2: Email Retrieval System Setup

Python script to fetch emails using IMAP: if the code has error or bug fixed with the help of chat gpt just access imap and retrieive email based on search. and format it the way you want it.
in the next step you wil learn how to use this function and convert it an api.

import imaplib

import email



def get_emails(temp_email):

    # Connect to Hostinger IMAP

    mail = imaplib.IMAP4_SSL('imap.hostinger.com', 993)

    mail.login('catchall@yourdomain.com', 'your_password')

    

    # Search for target emails

    mail.select('inbox')

    status, data = mail.search(None, f'(TO "{temp_email}")')

    

    emails = []

    for email_id in data[0].split():

        # Process each email

        status, msg_data = mail.fetch(email_id, '(RFC822)')

        raw_email = msg_data[0][1]

        msg = email.message_from_bytes(raw_email)

        

        # Extract email components

        email_info = {

            'subject': msg['subject'],

            'from': msg['from'],

            'body': get_email_body(msg)

        }

        emails.append(email_info)

    

    return emails

Step 3: Create Web Endpoints

FastAPI endpoints for email management:

from fastapi import FastAPI

import uuid



app = FastAPI()



//domain.com/new-email it will return new random email address

@app.get("/new-email")

def generate_email():

    """Create random email address"""

    return {

        "email": f"{uuid.uuid4().hex[:8]}@yourdomain.com",

        "inbox_url": "/inbox/{email}"

    }



//domain.com/inbox/emailhere and it will return all the email

@app.get("/inbox/{email}")

def get_inbox(email: str):

    """Retrieve messages for specific email"""

    return {

        "email": email,

        "messages": get_emails(email)

    }

Security Considerations

• 🔒 Always use environment variables for credentials
• 🚫 Never expose your admin email publicly
• ⏲️ Implement automatic email expiration
• ⏲️ delete old email in 60 minutes.
• 📉 Add rate limiting to your API endpoints
• always secure your api endpoint with api key or with token

Next Steps

You now have a functional temporary email system! To enhance it:

1. Add web interface with HTML templates
2. Implement email content filtering
3. Set up automatic cleanup cron job
4. Add SMTP support for sending emails if needed but not necessary if you only want to receive email and not sending it
