Add the following to the snmpd.conf file and reload snmpd deamon

extend queuecheck /etc/queuecheck.sh

Run snmpwalk will produce the below result and verified by mailq Total request .

#snmpwalk -v2c -c public localhost NET-SNMP-EXTEND-MIB::nsExtendOutputFull

NET-SNMP-EXTEND-MIB::nsExtendOutputFull."queuecheck" = STRING: No of emails in mail queue if zero it will report /var/spool/mqueue
