Filesystem            Size  Used Avail Use% Mounted on
/dev/sda2              33G  2.6G   30G   9% /
tmpfs                 189M     0  189M   0% /lib/init/rw
udev                   10M  564K  9.5M   6% /dev
tmpfs                 189M     0  189M   0% /dev/shm

That's on a production Postfix firewall/gateway.  The mail spool is located on /
and as you can see /home is mounted on a separate 100GB partition.  I don't
suspect I'll ever be close to filling up / on this machine, given the 30GB of
free space, 72GB free in /home, and 350GB of unpartitioned space on the 500GB disk.

As Osamu said, always keep user file areas on a partition separate from your
mail spool and log partitions, which are normally located in /
