find and remove mails from spammer in exim-out queue

Due to spamming, spoofing from clients, etc., etc., etc., I am finding it necessary to spend more time to clear the exim queue from time to time.
go to /var/spool/exim/input
#grep -r “SPAMMER@yourdomain.com” ./ |awk ‘BEGIN { FS = “:” } ; { print $1 }’  |xargs rm
