SMF For Free Support Forum

since my smf for free forum opened, my e mail from there has always gone to my junk box, no matter what...i have even repeetedly put it on my safe list...but to no avail seems to end up in my junk. MasterBooziesBlueStarLounge <mcm_bates@msn.com> is in the header.  I really dont understand, because i receive e mails from another smf for free site and dey do not go to my junk. I have even had trouble with some of my members gettin their e-mails from the site in changin their passwerds. also have had 2 problems with members joining an never getting an e mail (they were non hotmail accounts) so i changed to immediate registration. But still have trouble with some if they forget their passwerd or needs or wants a name change. What can I do to change this?? is it something on my end.
My site is in my signature
