Recieving Mail From Two Seperate Domains

Hello all, our company bought out another companies assets and changed the company name. So now we have two domain names. Right now we have a Windows box setup with Small Business Server running Exchange to receive mail for our new company name. However, we still want to receive mail from the old company name that was hosted on GoDaddy. Is there a way to setup our Exchange server to receive mail from both domain names?
