Hi, experts,
I need to write a mail tracking software for a publishing company (they can not use an emailing service for legal reasons). I am planning to embed a small image from their server and track each request to this image. I plan to return the image through a servlet, and in this way I will get notified. I am also planning to use Apache Tomcat and JSP. The reporting requirements are not complex, and I do not expect more than 100,000 emails in each mailing, so probably one server can handle the load.
Is that a good approach? Can you give me some corrections? What are the gotchas and what should I be looking out for?
Thank you.
