Replying to a message from: David

I currently use Hostmonster to host my domain name (shrydvd.com). The only thing I really use it for though is the email. I am looking for a solution that would allow me to keep my email as shrydvd.com without having to pay so much for complete domain hosting. My thought is that I could set Xeams up on my home computer and use it to host shrydvd.com only for email. I could then cut ties with anyone else. Is this correct or am I being overly simplistic? Thank you,
