Interpreting Log Files


Nov 13, 2006
Just a few days ago I had the cPanel Server Service Packages installed on my server. It looks quite nice and I'm happy with MailScanner, but I've got several issues. For one sending e-mail broke down after the installation, but that will hopefully soon be fixed. Most importantly I am now getting hourly system check overview e-mails, which is nice but only if I really knew how to interpret them. What do you guys recommend to read in order to better understand these errors? I'd like to learn more about it.

On the short term, I'm getting over a hundred Unusual System Events every hour, and several Security Violations as well (either "unexpected RCODE (REFUSED)" or "failed to expand condition "${perl{checkspam}}" for lookuphost router"); is this normal??
