Two problems.  

One; it's not 22246 bytes; it's 22246 512-byte blocks ~= 11 MB.  "du"
output becomes a lot easier to understand if you set your environment
variable "BLOCKSIZE=1k".

Two; "du" prints cumulative usage totals.  The last entry - "." is the
total usage in the directory.  Most of the space is actually taken up
by your mail/ directory.

If you plan on keeping a large inbox like this, you might want to move
/var/mail to /usr/mail and make a symlink for /var/mail -> /usr/mail,
or possibly repartition your disk with a larger /var.
