I personally use web based e-mail most of the time but then i dont email too much. But at school, we have Pegasus mail which is a free download from http://www.pmail.com . It is fully compatible with XP. Also, you could try Eudora (http://www.eudora.com/download/) but i think they have some minor issues with XP still, but they say they are working on them. Its also free. Hope this helps
