How to Install and Use ssmtp to Send Emails from the Linux Terminal

ssmtp is a simple utility that can be used to send emails from a Linux system to a specified email address. It is just an MTA (Mail Transfer Agent); it does not receive mail, expand aliases, or manage a queue. Instead, it forwards automated emails to an external email address. This can be useful for forwarding system alerts or other automated emails from your system to an external email address.
