Is it a correct way to clear the exim mail queue?

I use the following command to delete the exim mail queues exiqgrep -i | xargs exim -Mrm or # following commands seems to work faster compared to the above. exim -bpru | awk {'print $3'} | xargs exim -Mrm But the above commands do not work when the mail queue size is more than 100,000. It get stuck. So, I am using the following script which works fine regardless of the number of mails in the queue. My question is, will it delete correctly ? /etc/init.d/exim stop; sleep 10; killall -9 exim eximd sleep 5; #clean out the mail queue find /var/spool/exim -mindepth 2 -type f -exec rm -rfv {} \; #clean out the mail db files find /var/spool/exim/db -type f -exec rm -rvf {} \; /etc/init.d/exim restart
