How to configure Postfix on your Raspberry Pi?

The latest version of Raspbian is now out and it is called Jessie. In this blog, we are going to see how to configure Postfix on your Raspberry Pi. You may be thinking that what is the difference between Raspbian and Jessie. It means that Jessie is the latest version of Raspbian.


So, what is Postfix?


It is an email server and it is used for sending emails from your computer to other computers. The main purpose of installing Postfix on your Raspberry Pi is to send emails from your Raspberry Pi to other computers and devices.


Let’s see how to configure Postfix on your Raspberry Pi.


How to configure Postfix on your Raspberry Pi?



The first thing that you need to do is to install the dependencies of Postfix. $ sudo apt-get install postfix Now, we need to create a Postfix user and group. $ sudo adduser postfix $ sudo addgroup mail After creating these two users, we will need to set a password for the Postfix user. $ sudo passwd postfix Now, we need to set the Postfix mail path. You can use either /var/mail or /var/spool/mail.


So, we have set the Postfix mail path. Now, we need to edit the main.cf file. $ sudo nano /etc/postfix/main.cf Now, in the main.cf file, we need to add some settings like the hostname, the port number, the smtp_tls_security_level, and the smtp_use_tls option. #hostname = raspberrypi.local #port = 25 #smtp_tls_security_level = may #smtp_use_tls = yes Now, we need to restart the Postfix service. $ sudo systemctl restart postfix.


You can check whether Postfix is working properly or not by checking the following things:


  • Check your email account on Gmail, Yahoo, and other mail providers.
  • Check the incoming and outgoing emails on the console.
  • You can also check the mail logs in /var/log/mail.log.
  • You can check the Postfix configuration file by using the command: $ sudo cat /etc/postfix/main.cf


Conclusion:


We have configured the Postfix server on our Raspberry Pi. Now, you can send and receive emails from your computer to other computers and devices.
