Hello, I host a close friends website and I have just noticed his bandwidth usage was normally around 1.5GB - 2GB max per month... Then all of a sudden looking at the logs last october his bandwidth usage shot up to 25GB per month. Looking at the attached files it seems to be due to POP... Now he only has 1 mailbox on this domain which I include some output from below: [~]# grep Domain-name-in-question /var/log/maillog* | grep retr= | grep -v retr=0 | awk {'print $11'} | cut -d, -f1 | cut -d= -f2 | awk '{t += $1} END { print "total: ", t, " bytes transferred over POP3"}' total: 26077432943 bytes transferred over POP3 (24GB) This tallys up with what cPanel bandwidth monitor is telling me. Then I did the following: [~]# grep Domain-name-in-question /var/log/maillog | grep retr= | awk {'print $7" "$1" "$2" "$3" "$11'} | grep -v retr=0 user=Domain-name-in-question, Feb 9 03:37:25

How do I determin what IP is doing this and if it is a script / program on the users site doing this? Many Thanks Nick,

  Hello :) You should see the IP address of user who made the POP3 connection in the /var/log/maillog file. Try modifying the "grep" command in the bash script you are using so the IP address is output. Thank you.
