To send emails on linux to other remote email addresses, we will first need to install the
postfix server and
sudo apt-get install mailutils # For debain & Ubuntu
During the installation, a prompt similar to this should pop up:
This the configuration panel for postfix, and for our case, we need to select the option
If you accidentally falsely configure postfix, you can reconfigure it via the command:
sudp dpkg-reconfigure postfix
After finish installing mailutils, you now should be able to send an email! Try:
mail -s "Hello World!" YOUR@EMAIL << "Across the Great Wall we can reach every corner of the world."
For further detail into the
man mail to explore all the options it has.
