How to Set Up a Mail Server Using a Script

Setting up your own mail server might seem like a daunting task, but with the emailwiz script, you can simplify the process significantly. This guide will walk you through how to configure a mail server on a Debian or Ubuntu server using emailwiz, which automates the installation and setup of all necessary components including Postfix, Dovecot, Spamassassin, OpenDKIM, Certbot SSL, and Fail2ban.

Prerequisites

Before you start, ensure that you have:

1. A Server with Debian or Ubuntu:

   • SSH access to the server with root privileges or a user with sudo rights.

2. DNS Records:

   • Properly configured DNS records for your domain, including A record, MX record, and records for SPF, DKIM, and DMARC.

Step 1: Prepare the Server

1. Update the Package Manager:

   bash

   Копировать код

   sudo apt update && sudo apt upgrade -y

2. Install Git:

   bash

   Копировать код

   sudo apt install git -y

Step 2: Download and Run the emailwiz Script

1. Clone the emailwiz Repository:

   bash

   Копировать код

   git clone https://github.com/LukeSmithxyz/emailwiz cd emailwiz

2. Run the Installation Script:

   bash

   Копировать код

   sudo ./emailwiz.sh

Step 3: Follow the Installer’s Instructions

During the script execution, you will need to:

1. Enter Your Domain:

   • Ensure that your DNS records are correctly set up for this domain.

2. Install Certbot for SSL Certificates:

   • The script will automatically install Certbot and configure SSL certificates for your domain.

Step 4: Verify the Installation

Once the installation is complete, the emailwiz script will automatically configure and start all necessary services. You can check the status of the services with the following commands:

1. Postfix:

   bash

   Копировать код

   systemctl status postfix

2. Dovecot:

   bash

   Копировать код

   systemctl status dovecot

3. Spamassassin:

   bash

   Копировать код

   systemctl status spamassassin

4. OpenDKIM:

   bash

   Копировать код

   systemctl status opendkim

5. Fail2ban:

   bash

   Копировать код

   systemctl status fail2ban

Step 5: Configure Your Email Client

Now that your mail server is set up and running, you can configure your email client (e.g., Thunderbird, Outlook, or any other client) to send and receive emails through your new server.

• Incoming (IMAP/POP3) Servers:

  • Server: mail.yourdomain.com
  • Port: 993 (IMAP with SSL) or 995 (POP3 with SSL)
  • Encryption: SSL/TLS

• Outgoing (SMTP) Server:

  • Server: mail.yourdomain.com
  • Port: 587 (SMTP with STARTTLS)
  • Encryption: STARTTLS

Conclusion

The emailwiz script greatly simplifies the process of setting up and configuring a mail server. By following these steps, you can quickly deploy a fully functional, secure, and efficient mail server on Debian or Ubuntu.
