If /usr/spool/mail (/usr/mail on System V) is writable, then people can remove
other people's mailboxes. Admittedly, the "sticky directory" idea that is in
one of the Berkeley systems (i.e. "+t" on directory means you can only unlink
files that you own) helps this.

I would hope that people on your system aren't malicious enough to do this, but
an accidental "rm -f" in the wrong directory can do wonders.
