How to Delete email containing a specific email address or string 

find /var/mailcleaner/spool/exim_stage1/input -exec grep -q 'email@dominio.com' '{}' \; -delete

It is possible to create a simple shell script to delete all the queue:

#!/bin
if [ -z $1 ]
then
echo "Insert the E-Mail address or a string to find it in mailqueues and delete all the email with it"
read STRING
else
STRING=$1
fi
find /var/mailcleaner/spool/exim_stage1/input -exec grep -q $STRING '{}' \; -delete
find /var/mailcleaner/spool/exim_stage2/input -exec grep -q $STRING '{}' \; -delete
find /var/mailcleaner/spool/exim_stage4/input -exec grep -q $STRING '{}' \; -delete
echo "Process ended"
script usage:
/usr/bin/perl /bin/queue-delete.sh $STRING

where $string is the email or string to search for deletion
