How To Send Emails From An Ubuntu Machine Using Gmail

An easy way to send emails from an Ubuntu machine for things such as system alerts is by using SSMTP.

Install and configure SSMTP

Start by installing the ssmtp package by running:

sudo apt-get install ssmtp

Once complete, edit the configuration file by located at /etc/ssmtp/ssmtp.conf (I use nano as my editor):

sudo nano /etc/ssmtp/ssmtp.conf

Edit the field that states

# root is the person who gets all mail for userids < 1000

so that you can receive the emails and add the following information to the bottom of the file (editing the AuthUser and AuthPass):

# Gmail Information

Time to test

Now it’s time to test and make sure everything works. Run the following command making sure to edit the email field to match your information:

echo "Test message from Linux server using ssmtp" | sudo ssmtp -vvv [email protected]

You should now receive an email from your server. If so, you have successfully configured your server to send emails using SSMTP!
