Email Hosting

Hi, i have a website with easyspace and they are hosting it, only now i have changed the domain name but easyspace are unable to transfere the domain name, at the moment i am just using framed web forwarding. and email forwarding, but when i reply to a email it uses the old domain as the recipient.

However, i have a reseller account where i could host my domain, but what i want to know is how can i use framed web forwarding as when the domain has its name servers changed?

In other words i wnat to keep web forwarding, but host the domain for email?
