From James Dooley's Wiki
Overview
This script is set up to copy the current php.ini file to a users directory and block web users from being able to view it in .htaccess.
There are two versions of this script, one for SuPHP one without.
Script
for address in $(grep ${DOMAIN} maillog | grep pop3d| awk '{print $7}' | cut -d "=" -f2 | sed 's/,//' | sort | uniq);
do grep $address maillog* | grep `date +%b` | grep pop3d | grep LOGOUT | awk '{print $13}' | cut -d "=" -f2 | sed 's/,//' | awk '{total=total+$1}END{print total}' | xargs echo "$address: ";done | sort -k 2 -nr
What to change
${DOMAIN} will need to be changed for the domain name you want to search for
pop3d can be changed to look at imap instead.
