myhostname = tempmail.example.com
mydomain = example.com
myorigin = $mydomain
inet_interfaces = all
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain

# Virtual domain configuration
virtual_alias_domains = tempmail.example.com
virtual_alias_maps = hash:/etc/postfix/virtual

# Custom delivery for temporary emails
mailbox_command = /usr/local/bin/tempmail-delivery.py
            

Custom Email Delivery Script

A custom delivery script processes incoming emails and stores them in the temporary email system database. This script handles email parsing, storage, and integration with the web application backend.

#!/usr/bin/env python3
# tempmail-delivery.py - Custom email delivery script

import sys
import json
import email
import psycopg2
from datetime import datetime, timedelta

def process_email():
    # Read email from stdin
    raw_email = sys.stdin.read()
    msg = email.message_from_string(raw_email)
    
    # Extract email details
    to_address = msg['To']
    from_address = msg['From']
    subject = msg['Subject']
    body = get_email_body(msg)
    
    # Store in database
    store_email(to_address, from_address, subject, body)

def store_email(to_addr, from_addr, subject, body):
    conn = psycopg2.connect("dbname=tempmail user=tempmail")
    cur = conn.cursor()
    
    # Set expiration time (10 minutes from now)
    expires_at = datetime.now() + timedelta(minutes=10)
    
    cur.execute("""
        INSERT INTO emails (to_address, from_address, subject, body, expires_at)
        VALUES (%s, %s, %s, %s, %s)
    """, (to_addr, from_addr, subject, body, expires_at))
    
    conn.commit()
    conn.close()

if __name__ == "__main__":

Database Design and Schema

Effective database design is crucial for temporary email services that must handle high volumes of emails while maintaining fast query performance and automatic cleanup capabilities. The database architecture team at 10MinuteMailGuide.world has developed optimized schemas for temporary email storage and management.

Core Database Schema

The database schema must efficiently store email data while supporting fast lookups and automatic expiration. Consider indexing strategies and partitioning for high-volume deployments.

-- PostgreSQL schema for temporary email service
CREATE TABLE emails (
    id SERIAL PRIMARY KEY,
    to_address VARCHAR(255) NOT NULL,
    from_address VARCHAR(255) NOT NULL,
    subject TEXT,
    body TEXT,
    html_body TEXT,
    attachments JSONB,
    created_at TIMESTAMP DEFAULT NOW(),
    expires_at TIMESTAMP NOT NULL,
    read_at TIMESTAMP
);

-- Indexes for performance
CREATE INDEX idx_emails_to_address ON emails(to_address);
CREATE INDEX idx_emails_expires_at ON emails(expires_at);
CREATE INDEX idx_emails_created_at ON emails(created_at);

-- Automatic cleanup function
CREATE OR REPLACE FUNCTION cleanup_expired_emails()
RETURNS void AS $$
BEGIN
    DELETE FROM emails WHERE expires_at < NOW();
END;
$$ LANGUAGE plpgsql;

-- Schedule cleanup every minute
SELECT cron.schedule('cleanup-emails', '* * * * *', 'SELECT cleanup_expired_emails();');
            

Backend API Development

The backend API provides the interface between the frontend application and the email storage system. A well-designed API ensures efficient email retrieval, proper security controls, and scalable performance. The API development framework from 10MinuteMailGuide.world covers essential endpoints and implementation patterns.

Essential API Endpoints

The temporary email service API requires several core endpoints to support email generation, retrieval, and management functionality. Each endpoint should implement appropriate security measures and error handling.

POST /api/generate

Generate a new temporary email address with configurable expiration time and domain selection.

GET /api/emails/{address}

Retrieve all emails for a specific temporary address with pagination and filtering options.

GET /api/email/{id}

Fetch a specific email by ID with full content including attachments and HTML formatting.

DELETE /api/emails/{address}

Manually delete all emails for a temporary address before natural expiration.

Node.js API Implementation Example

Here's a sample implementation of the core API endpoints using Node.js and Express.js with PostgreSQL integration:

const express = require('express');
const { Pool } = require('pg');
const crypto = require('crypto');

const app = express();
const pool = new Pool({
    connectionString: process.env.DATABASE_URL
});

// Generate temporary email address
app.post('/api/generate', async (req, res) => {
    try {
        const { domain = 'tempmail.example.com', duration = 10 } = req.body;
        
        // Generate random email address
        const randomString = crypto.randomBytes(8).toString('hex');
        const emailAddress = `${randomString}@${domain}`;
        
        // Calculate expiration time
        const expiresAt = new Date(Date.now() + duration * 60 * 1000);
        
        res.json({
            email: emailAddress,
            expires_at: expiresAt,
            duration_minutes: duration
        });
    } catch (error) {
        res.status(500).json({ error: 'Failed to generate email' });
    }
});

// Retrieve emails for address
app.get('/api/emails/:address', async (req, res) => {
    try {
        const { address } = req.params;
        const { page = 1, limit = 20 } = req.query;
        
        const offset = (page - 1) * limit;
        
        const result = await pool.query(`
            SELECT id, from_address, subject, created_at, read_at
            FROM emails 
            WHERE to_address = $1 AND expires_at > NOW()
            ORDER BY created_at DESC
            LIMIT $2 OFFSET $3
        `, [address, limit, offset]);
        
        res.json({
            emails: result.rows,
            page: parseInt(page),
            total: result.rowCount
        });
    } catch (error) {
        res.status(500).json({ error: 'Failed to retrieve emails' });
    }
});

app.listen(3000, () => {
    console.log('Temporary email API running on port 3000');
});

                    <p>No emails received yet. Waiting for incoming messages...</p>
                ) : (
                    emails.map(email => (
                        <div key={email.id} className="email-item">
                            <h3>{email.subject}</h3>
                            <p>From: {email.from_address}</p>
                            <p>Received: {new Date(email.created_at).toLocaleString()}</p>
                        </div>
                    ))
                )}

Rate Limiting and Abuse Prevention

Implementing effective rate limiting prevents abuse while maintaining service availability for legitimate users. Consider multiple rate limiting strategies including IP-based limits, email generation limits, and request frequency controls.

const rateLimit = require('express-rate-limit');
const RedisStore = require('rate-limit-redis');
const redis = require('redis');

const client = redis.createClient();

// Rate limiting for email generation
const generateEmailLimiter = rateLimit({
    store: new RedisStore({
        client: client,
        prefix: 'rl:generate:'
    }),
    windowMs: 15 * 60 * 1000, // 15 minutes
    max: 10, // Limit each IP to 10 email generations per windowMs
    message: 'Too many email addresses generated, please try again later.'
});

// Rate limiting for API requests
const apiLimiter = rateLimit({
    store: new RedisStore({
        client: client,
        prefix: 'rl:api:'
    }),
    windowMs: 1 * 60 * 1000, // 1 minute
    max: 100, // Limit each IP to 100 requests per windowMs
    message: 'Too many API requests, please try again later.'
});

app.use('/api/generate', generateEmailLimiter);
app.use('/api/', apiLimiter);
