Email being blocked?

I am using the FSCF plugin, and it seems to work fine except that it will not send (or maybe I’m not receiving) contact info to an email addresses associated with my wordpress domain. It will send email to my yahoo email,and I receive it, but when I put in the email address for my Dreamhost hosted wordpress domain, I never recieve it. I’ve tested the dreamhost domain email and it sends and recieves email outside of FSCF without any problems. Is there something I need to do?
