We are website provider and we find that some of the hosted website cause email bounced. Under further investigation, we find that a website has been use <frame> ... </frameset> and within the frameset, there is a redirection to use a php on another website - the original designer of the website.
Is it possible to disable frameset, or website redirection ? I am asked to review the existing infrastructure and give immediate action.
1. Is there any tools to to rescan all our existing websites and identify this kind of problem ?
2. Any solution to remedy this problem ?
