Terminal question: "You have mail."

What happens if you type mail?

 

You'll be able to read it if you type mail like Mitthrawnuruodo suggested. This is a system level mail that's used for alerting users to things. I forget now but there are a couple of activities that you can do that will generate a mail message for the admin. It might be something related to system housekeeping. I thought it was sudo'ing from a non admin account, but that apparently isn't one if them.

 

Those messages are being sent by ClamXAV or some other implementation of Clam antivirus, right? Yes, basically. Delete them after you read them. They just mean what they say. As long as it's not consistently failing to get virus definition updates, you should be fine.

 

Instructions on how to solve the issue

Synopsis

As Mitthrawnuruodo and mkrishnan already said, it is a system level email.
I also had this issue, and found out where to check for for it.
You can use the following guide.

Good luck!

Instructions for Terminal.app (aka the command line shell)

Go to the directory (=folder) where the system level email files for all users are stored, and list them:

cd /private/var/mail/; ls -l

Display the email(s) for the user which you fill into <username>.
Either use your username (without the angle brackets) or use the character * (asterisk) if you want all emails from users listed:

cat <username> | less

Finally erase your mail file, in case you do not need it anymore.

sudo rm /private/var/mail/<username>
