Delay Mail Sending

Hello,

I wanted to know how I can setup a mail flow so every one in our organization who sends an email dont have this OH NO!! moment after sending an email out, I know I can do this via Outlook, but I wanted to know if this can be done via exchange powershell or ecp so its setup globally.

Delay emails by like 2 minutes for emails going out.

Thank you for your time and your assistance.
