Mail notification under csh on R6000?

[Bruce Johnson]

While mail notification seems to work fine under ksh, we have
been unable to get it to work under csh, which many of our
users use as their login shell.  Putting the environmental
variable MAIL to, e.g., "5 /usr/spool/mail/username" as described
in the "man pages" for csh doesn't seem to accomplish much.  Is
this a FAQ?
