I think the server of columbia.edu is make your yahoo id spam and he block the addres so you not receive the mails from here.


You could try to send a mail from your yahoo accout to columbia.edu server and then reply the same mail columbia.edu server to yahoo account. Or contact the columbia.edu to inform that this address is not spam.
