The command swaks is a utility used for testing SMTP servers. It simulates sending emails and helps with diagnosing issues. Let's break down the command:
swaks: This is the command to run the swaks utility.
--to ${user@example-com}: This option specifies the recipient email address for the simulated email. You need to replace ${user@example-com} with an actual email address.
--body ${path-to-gtube_file}: This option specifies the body of the email. It requires the path to a file that contains the content to be included in the email. You need to replace ${path-to-gtube_file} with the actual path to the file.
So, by running this command, you are telling swaks to send a simulated email to the specified recipient with the content from the file specified.
