Sometimes when opening your terminal, it will say:
You have new mail.
This is usually just noise. A local dev environment probably tried to send email and failed because cron wasn’t configured.
Usage
# Enter the `mail` program
mail
# Read a message (by its number)
5
# Delete a message (by its number)
delete 5
# Delete all messages
delete *
# Exit the `mail` program
