Postfix is a mail transfer agent (MTA), an application used to send and receive email. It can be configured so that it can be used to send emails by local application only. In this tutorial, you'll install and configure Postfix on Ubuntu 20.04 as a send-only SMTP server. You'll also request free TLS certificates from Let's Encrypt for your domain and encrypt the outbound emails using them.
