I have a C++ application that will be run on my clients' destops. Before running my application, my clients are required to perform the activation process, which will cause my app to send an email back to me. I had some code in my app to send mail back to me but it only works if an smtp server is defined. I was just wondering if there is a way for me to determine my users' stmp server automatically through coding?
Thank you very much for you help. Some coding example would be helpful.
