We have two servers running Plesk 8.3, versions: - 8.3.0 CentOS 4.3 83080131.20 - 8.3.0 CentOS 5 83080131.20 (a recent install from scratch) Both servers are reporting 0 Kb POP3/IMAP traffic in the per-domain bandwidth usage report. FTP,HTTP and SMTP reporting is working correct. I tried to find out where Plesk should get the information to calculate the POP3 and IMAP traffic, but I couldn't find out. The file /usr/local/psa/var/log/maillog does not report the sizes of the messages, should it do that? Is there an other log where Plesk gets the information to calculate the POP3/IMAP traffic? I assume the POP3/IMAP traffic calculation is done by the /usr/local/psa/admin/sbin/statistics command from the file /etc/cron.daily/50plesk-daily, is that true? On this forum I have found several threads reporting the same problem, none with a solution: http://forum.swsoft.com/showthread.php?t=10421 http://forum.swsoft.com/showthread.php?t=16778 http://forum.swsoft.com/showthread.php?t=26897 http://forum.swsoft.com/showthread.php?t=35284 Please help us!
