Setting up Debian Jessie Email Server Dnsmasque

Installation of DNSmasque

The first step in setting up an email server on Debian Jessie is installing DNSmasque. DNSmasque is a lightweight DNS server that is easy to set up and configure. To install DNSmasque, follow these steps:

  1. Open the Terminal and enter the command: sudo apt-get update to update the package list.
  2. Enter the command: sudo apt-get install dnsmasq to install DNSmasque.
  3. Once installed, open the DNSmasque configuration file by entering the command: sudo nano /etc/dnsmasq.conf.
  4. Edit the configuration file to include the following lines:

domain-needed

bogus-priv

mx-host=example.com,mail.example.com,0

address=/mail.example.com/192.168.0.1

The above configuration file tells DNSmasque to use the domain name mail.example.com for the email server, and set the IP address to 192.168.0.1. Replace example.com with your registered domain name and the IP address with your server’s IP address.

Installation of Postfix

The next step is installing Postfix, an open-source mail transfer agent (MTA), that will transfer emails from your server to the email client. Follow these steps to install Postfix:

  1. Open the Terminal and enter the command: sudo apt-get install postfix.
  2. You will be prompted to select the Internet Site configuration. Select this option and enter your domain name when prompted.
  3. Next, open the Postfix configuration file by entering the command: sudo nano /etc/postfix/main.cf.
  4. Edit the configuration file to include the following lines:

myhostname = mail.example.com

mydestination = mail.example.com, localhost.localdomain, localhost

mynetworks = 192.168.0.0/24 127.0.0.0/8

inet_interfaces = all

Replace example.com with your registered domain name, and the IP address with your server’s IP address.

Installation of Dovecot

The final step is installing Dovecot, a mail delivery agent (MDA), that will store the emails on your server and enable you to access them through an email client. Follow these steps to install Dovecot:

  1. Open the Terminal and enter the command: sudo apt-get install dovecot-common dovecot-imapd.
  2. Next, open the Dovecot configuration file by entering the command: sudo nano /etc/dovecot/dovecot.conf.
  3. Edit the file to include the following lines:

mail_location = maildir:/var/mail/vhosts/%d/%n

auth_mechanisms = plain login

disable_plaintext_auth = no

The above configuration file tells Dovecot to store emails in the /var/mail/ directory and allows users to login with plain text authentication. You can change the directory path to your preferred location.

Once you have completed the above steps, you have successfully set up Debian Jessie Email Server Dnsmasque.
