3.6 Changing the default RMAIL file

By default, the mailer attempts display and place new mail into a file called
~/RMAIL . If your mail file is on another machine, or you wish to read another mail file when you start up the mail reader, you need to set the appropriate mailer resource. For example:

(setf lw:*default-rmail-file*

You may wish to include this in your initialization file, so that it is read every time you start the environment.
