How to Install and Configure Postfix as a Send-Only SMTP Server on Ubuntu 16.04

If you want to send emails from your Ubuntu 16.04 server, you can install and configure Postfix as a send-only SMTP server. In this tutorial, we will walk you through the steps to install and configure Postfix on Ubuntu 16.04.

Step 1: Install Postfix

First, update your system and install Postfix using the following command:

sudo apt-get update
sudo apt-get install postfix

During the installation process, you will be prompted to select the configuration type. Select "Internet Site" and enter your domain name when prompted. If you don't have a domain name, you can use your server's hostname.

Step 2: Configure Postfix

Next, open the Postfix configuration file using your preferred text editor:

sudo nano /etc/postfix/main.cf

Find the following lines and uncomment them by removing the "#" symbol:

# myhostname = example.com
# mydestination = example.com, localhost.example.com, , localhost
# relayhost =

Replace "example.com" with your domain name or hostname. Save and close the file.

Step 3: Restart Postfix

After making changes to the configuration file, restart Postfix using the following command:

sudo systemctl restart postfix

Step 4: Test Postfix

You can test your Postfix installation by sending a test email using the following command:

echo "This is a test email." | mail -s "Test Email" you@example.com

Replace "you@example.com" with your email address. If the email is sent successfully, you should receive it in your inbox.

That's it! You have successfully installed and configured Postfix as a send-only SMTP server on Ubuntu 16.04.
