check_eximailqueue_1.3 work well on me

first time execute check_eximailqueue_1.3, will appear this error :
./check_eximailqueue_1.3: line 36: /usr/local/nagios/libexec/utils.sh: No such file or directory
Mailqueue WARNING – query returned no output!

=> it means you need to :
1. modify your path on
. /usr/local/nagios/libexec/utils.sh to your own directory. for me, it is on /usr/lib64/nagios/plugins/utils.sh

2. modify path on
EXIM=/usr/local/exim/bin/exim
for me, it is on EXIM=/usr/sbin/exim
