Prevent spamming
This week one of my resellers signed up a new customer. After setting up the account the user uploaded a cgi script and some mailinglists and started spamming with the cgi script. It was some kind of bulk mailer.
I noticed the abuse because the serverload jumped from 0.1 to 7.0 and up. Also the mrtg graph made a big jump.
Also spam complaints came rolling in after that. Still a good thing i could disable the account so fast, was only running the script for 1 hour.
Is there a easy way to prevent this. Disabling cgi isn't an option ofcourse.
any suggestions
Thanks
