[opensuse-packaging] What settings are needed for seamonkey mail to show mail of localhost [linux]

Hello, This is a setting up a package question. I was unsure what forum to post this to. How can a mail client [eg. seamonkey mail client]show or list the contents of /var/spool/mail/root on localhost [127.0.0.1]. What settings are needed to do this? I attached existing screenshots of settings. Thanks Glenn # mailx shows: # mailx Heirloom mailx version 12.5 7/5/10. Type ? for help.
