[newbie] Program to check usage of mail box

[Vinay Kudithipudi]

Hello Newbies,
      I  was  wondering if there is a command in linux to see the mail
      usage of the users mail box (i.e no of messages and size of mail
      box)  or  if there is a script which I can put in my cron job to
      run at regular intervals. I am using Mandrake 7.1. Thank you.

Vinay.
