Directory Size problem

[Dan Track]

Hi

I've got a directory /var/spool/mqueue that is at 3.6G. The problem is
that I've deleted everything in the directory but the size reported
from du -hs is still reported as 3.6G. I've shutdown all potential
sevices that could possibly be using teh directory e.g sendmail,
httpd, syslog but it hasn't helped if I run an lsof or fuser against
the directory I get no connections listed.

Could someone please help me figure this weird problem out.

Thanks
Dan
