You probably want to do
find /var/spool/clientmqueue -type f -exec rm -f {} \+
to reduce your load or if your find(1) isn't POSIX compliant:
find /var/spool/clientmqueue -type f -print0 | xargs -0 rm -f
If the load is of a problem use nice(1). Though I thought sendmail
brings a way on its own to delete messages from the queue, which
I would then prefer to use.

You can't give 2 commands to find's -exec and

I strongly recommend mounting /tmp as nosuid,nodev *and* noexec,
especially on a server.
