How to send mail through Gmail On Ubuntu using ssmtp

 Postfix is a flexible mail server that is available on most Linux distribution. Though a full feature mail server, Postfix can also be used as a simple relay host to another mail server, or smart host

Requirements

• Ubuntu 20.04
• Valid Gmail or Google App credentials

Now, we need to test if we can use the Linux command-line to send an email using Gmail.

Use the following command to install the required packages.

# apt-get update
# apt-get install ssmtp -y

Edit the ssmtp.conf file to connect to our Gmail account.

# vi /etc/ssmtp/ssmtp.conf

root=manas.tri@gmail.com
mailhub=smtp.gmail.com:587
FromLineOverride=YES
AuthUser=manas.tri@gmail.com
AuthPass=************
UseTLS=YES
UseSTARTTLS=YES

In our example, we are using the Gmail account manas.tri@gmail.com.

In our example, the Gmail account manas.tri@gmail.com is using the password XXXXXXXXX<hidden>.

You need to change the Gmail account and password to reflect your account.

Use the following command to send an email using the command-line.

# echo "E-Mail from cactiserver" | ssmtp manas.tri@gmail.com

Check your Gmail inbox for the test message that you just sent.

Cheers. Your Configuration is done.
