Surely you mean /var/spool/mail?

                        ^^^^^^^^
That's merely for mail logs, /var/adm holds messages, wtmp etc.

And /usr/ucb.

This is what SunOS 4.1.x has:-

Config files		/etc
Single user bins	/bin
Single user root user	/sbin
Daemons (inet)		/usr/etc
Temporary files		/tmp

Per machine variable	/var
Spool directories	/var/spool
Mail spool		/var/mail
Big tmp			/var/tmp
Logfiles		/var/{adm,log}
Accounting files	/var/adm/acct
Crash dumps		/var/crash

Bins			/usr/{bin,5bin}
UCB bins		/usr/ucb
Library files		/usr/lib	
Pgms called by pgms	/usr/lib
Data files		/usr/lib
Shared libs		/usr/lib
Programmer's bin, lib	/usr/{bin,ucb,lib}
Arch. indep. data files	/usr/share
Manuals			/usr/man
Other stuff		/usr/var -> /var
			/usr/spool -> /var/spool
			/usr/adm
			/usr/tmp -> /var/tmp

I like separating the UCB stuff from the generic from the SYSV, and would go
further, adding a /usr/posixbin for all those commands for which the posix
version differs from the generic/BSD/SYSV.
