Hi,  Mail --help wont help you for this, run the man command for this :  man mail  , command to have more info on the mail command  anyways to read the mails for the root user use  mail -f /var/spool/mail/root        ---> you need to login as root to view this.
I got a warning on my NX4 box (its below) and it tells me to check the mail for root. I was wondering if there is some documentation on the "Mail" command? I have searched powerlink and found nothing yet. Seems i need to delete some of the mail and i need to know how.  Here is the Warning message:  Too many mail messages for user(s): root. This may occur              because some of the system components are not functioning as expected. 1. Run the "mail" command to check the mail messages. For more                 information about the "mail" command, refer to its man page.  If i do a mail --help i dont get much information on it.  Thanks
