Automatic notification of new mail

Mail and Messaging Guide
Chapter 2, Using e-mail

You can configure your environment so that you are notified whenever new mail is sent to you, even if you are not in mail. To do this, set the MAIL shell variable to the pathname of your system mailbox. For example, if you are using the Bourne or Korn shells, you might set:

   $ MAIL=/usr/spool/mail/login
   $ export MAIL

You must set the mail shell variable if you are using the C shell:

   $ setenv mail /usr/spool/mail/login

For details on how to set environment variables, see ``Setting environment variables'' in the Operating System User's Guide.
