When you're using lines like these in bed...

cat /var/log/maillog /var/log/local1.log | grep "disconnect from" | cut -f3 -d [ | cut -f1 -d] | sort | uniq -c | sort

cat /var/log/maillog /var/log/local1.log | grep NOQUEUE | awk '{print $12}' | sort | uniq -c | sort

... you're bound to not get any!!
