So I thought that someone was faking the sender header and sending spam. I added SPF and domain-key records to try to combat this. However, either hotmail and yahoo don't check these or they ignore them because I'm still getting spammed. 

I don't think anyone bothers with SPF any more - the only people with
valid records are usually spammers.
