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

    You have mail in /var/mail - use the mail command to read – Mark Nov 29 '14 at 19:05

It tells you that you have received some mails (for example, because of your configuration of cron).

The best way is to read this mail. Type mail: at least one mail should appear. You can read by typing its number ID. You can also directly delete it (or even multiple mails) by typing d 1-1344 (1-1344 being the range of your new mails' IDs). Leave mail with x.

  • You may need to use q instead of x, to save changes – zessx Jul 22 '18 at 13:48

    You slipped in an extra 1 digit. – john 23 hours ago

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

    this doesn't work in ~/.zshrc on mac OSX with oh_my_zsh. is there another zsh configuration file? is there a work around? – Conor Cosnett Jun 13 '17 at 21:49

So apparently some program (probably my MAMP) put an email in

/var/mail/

Deleting this message did the trick...

  • ugh… I'd been seeing that in terminal for so long it felt like it was just its way of saying 'Hello". Nice find. – Tetsujin Nov 29 '14 at 19:56

    So you feel like trashing the contents of your mailbox is a good idea? Do you also do this in real live? – Max Ried Dec 4 '14 at 6:53

    Well the mail in question was more a mistake by a local server. I am on Mac OS and my mails are stored somewhere else. So trashing this file was ok. If your actual mail is stored under /var/mail YOU SHOULD NEVER DO THAT... – Øle Bjarnstroem Dec 6 '14 at 12:11

Unsetting (or even changing the value of) MAILCHECK didn't stop the message printed when I open a terminal tab/window. I eventually stumbled on an answer on superuser that enables me to still see this mail when it's convenient, but skip the constant nag message.

In short, create a ~/.forward file and, on a single line, the path of a file you'd like to receive mail in. Later, you can still elect to read the mail with mail -f <new_mail_file>.

If you have more advanced needs, it looks like forward can also specify a script by setting the line to |script_path or "|script_path args". I haven't tried this, but it should make it pretty simple to route messages based on the script that produced them, convert/compact them into a simple summary logline, etc.
