A lot of people use Gmail daily to send and receive mail. The estimated number of global users in 2020 was 1.8 billion. Gmail works on the SMTP protocol over port number 587. In this article, I demonstrate how to configure your SMTP web server and send mail automatically from Ansible and using ansible-vault to secure passwords.

Encrypt your password file

The ansible-vault command creates an encrypted file where you can store your confidential details.
