SMTP Server

This project implements a simple SMTP server for sending and receiving emails without relying on third-party email services. It allows users to mock email functionality and test email-based workflows.

Features

• Send and receive emails locally.
• Mock email functionality for development and testing.
• Avoid reliance on third-party email providers.

Prerequisites

• Node.js installed on your system.
• Basic understanding of networking and SMTP protocols.

Installation

1. Clone the repository:

   git clone https://github.com/debanshup/SMTP_SERVER.git
   cd SMTP_SERVER

2. Install dependencies:

   npm install

Usage

1. Start the SMTP server:

   npm start

   The server will start and listen on the default port. You can modify the port in the code if needed.

2. Configure email client:

   • Use localhost as the SMTP server.
   • Set the same port as in the server.

3. Test sending an email:

   • Use any email client or a script to send an email to the server.
   • Example using nodemailer:

       const nodemailer = require('nodemailer');
       const transporter = nodemailer.createTransport({
     
               host: "localhost",
               port: 1025,
               secure: false, // Disable SSL for local server
               tls: {
               rejectUnauthorized: false, // Allow self-signed certificates
               },
               ignoreTLS: true,
               });
     
          transporter.sendMail({
            from: 'sender@example.com',
            to: 'receiver@example.com',
            subject: 'Test Email',
            text: 'Hello, this is a test!',
          }, (error, info) => {
            if (error) {
              return console.log(error);
            }
            console.log('Message sent: %s', info.messageId);
          });

Configuration

• Modify the port and other server parameters inside main.js.
• Add additional handlers for incoming emails if needed.
