email tracking software

[kadnan]

Hi

I have been given a task to develop an email tracking system by using Open Source technologies. in ASP.NET/IIS, it's being done by using HTTP Modules[http://msdn.microsoft.com/msdnmag/issues/02/05/asp/default.aspx] which intercept image requests on IIS but since I need solution for Apache/php, I am unable to find similar technique. Can you guide me how to do it in php?'

Thanks

are you just wanting to bug emails and see who opens them?
