I have setup mailutils and ssmtp in my Ubuntu system. I have configured /etc/ssmtp/ssmtp.conf with proper credentials.
For testing I ran this command
echo "This is a test" | mail -s "Test" mygmailidbut I'm getting an error:
mail: cannot send message: Process exited with a non-zero statusI do have special characters in my password.

You can not use external applications with your normal password, you must go to and create a special password to use with your mail sender.
