How to get rid of "You have new mail." in zsh I'm using zsh with prezto as my shell with iTerm as terminal app.

I always get the message "You have new mail" when opening a new prompt. I don't have any new mail in Mac Mail and I don't run a mail server.

How can I get rid of this message?

Thanks
Whether zsh checks for new mail can be adjusted through the MAILCHECK parameter as described in zshparam(1). It specifies the interval in seconds between checks for new mail, a zero turns off the checks completely. So just put this into your zsh configuration file:

# don't check for new mail
MAILCHECK=0
