xfrom: A mail notification tool.             (c) Deniz Yuret, 1998

I do not like xbiff.  It shows you there is mail, but does not tell
you from whom.  Is it your advisor, or is it one of your students?
Of course you can use the from command.  But that does not tell you
who the mail was sent to: personally to you or to one of the stupid
mailing groups you are a member of?  As a result none of these tools
tell you how urgent this message is and whether you should stop
coding and start reading your mail.  So I wrote xfrom.  It displays
who your messages are from and who they were sent to.  You can also
click on any of the messages to get a preview.  Just make sure that
the MAILBOX_DIRECTORY is correct for your system.
