I think you will find that /usr/spool is a symbolic link to /var/spool
(i.e. spool -> ../var/spool).
As a result your mail is actually in your root partition where /var is
located.  I had problems with my mail and print spools flooding my root
partition and crashing my machine that I made a separate partition for
/var (I used the d partition).  The only problem with this is that you
need to remember to "mount /var" whenever you boot up in single user.
