   Let's ask a silly question here: do you have world read permissions
turned off on /dev/kmem?  I had a similar problem when closing up kmem
permissions, and it turns out that Ultrix does some sort of really strange
(and broken) locking on mail files... and the locking is load-dependent.
If it can't get at /dev/kmem, /bin/mail loses.

   There's a whole pile of MH commands that have similar problems.
