There are too many variable as to why email gets sent to spam folder. Do you have reverse dns and domain keys setup. Even with that I've had servers send spam to yahoo junk.

If you really want to eliminate all of your spam I would recommend setting up greylisting on your server. Then you can remove your spam-folder and not have that issues anymore. http://serverintellect.com/greylisting
