/usr/bin/mail needs to be able to read /dev/kmem.  On older versions
of ULTRIX (pre 4.0) /dev/kmem is world-readable.  If someone
makes it unreadable, local mail will notbe delivered.

Going out on the limb here (no guts, no glory as they say) as the
original poster hasn't gotten back to me to say if things are
fixed. However, most certainly things won't work if /usr/bin/mail
cannot read /dev/kmem.  

(/usr/bin/mail reads kmem to find out what the load average is
to decide how to deliver the mail.)
