blocked using dsn.rfc-ignorant.org

We're all getting this error when trying to send messages to a local university. They said we have to work it out with rfc-ignorant.org.

"Service unavailable; Sender address [RGT@mydomain.com] blocked using dsn.rfc-ignorant.org; Not supporting null originator (DSN)>"

Anyone know how I can resolve this?

Thanks
