To me this looks like a spam preventing measure from Hotmail because sending to Yahoo works.
I could imagine that you don't have a proper PTR record or SPF record fro your domain, that's why Hotmail refuses to accept your mail - with one exception: if a Hotmail user sends you a mail, and you reply to that mail, then Hotmail seems to recognize that this was initiated by a Hotmail user and therefore thinks that this isn't spam.
I'd contact the Hotmail support and ask what could cause this trouble.
