In this tutorial, we will learn how to configure SMTP (Simple Mail Transfer Protocol) on a Raspberry Pi. SMTP allows you to send email notifications or alerts from your Raspberry Pi projects or applications. By following these steps, you’ll be able to set up SMTP quickly and easily.
Requirements:
- Raspberry Pi
- Internet connection
Step 1: Update your Raspberry Pi Open a terminal and run the following commands
Step 2: Install the necessary packages In the terminal, enter:
sudo apt update sudo apt upgrade
sudo apt install ssmtp mailutils
Step 3: Configure SSMTP Enter the following command to open the configuration file:
sudo nano /etc/ssmtp/ssmtp.conf
Replace the file’s contents with the following:
root=your-email@example.com
mailhub=smtp.gmail.com:587
rewriteDomain=gmail.com
hostname=your-hostname
UseTLS=YES
UseSTARTTLS=YES
AuthUser=your-email@example.com
AuthPass=your-email-password
FromLineOverride=YES
Replace your-email@example.com
with your email address, your-email-password
with your email password, and your-hostname
with a desired name to identify your Raspberry Pi.
Step 4: Save the changes and exit the editor.
Step 5: Configure the mail name Open the revaliases file by entering:
sudo nano /etc/ssmtp/revaliases
Replace the existing contents with:
pi:your-email .com:smtp.gmail.com:587

sudo nano /etc/hostname
Replace the existing hostname with the name you specified in the ssmtp.conf
file.
Step 7: Update the hosts file Open the hosts file by entering:
sudo nano /etc/hosts
Replace the existing hostname with the name you specified in the ssmtp.conf
