I am receiving the following error when a new user signs up for an account:

"Failed to add recipient: cath...@wrighcity.k12.mo.us [SMTP: Invalid
response code received from server (code: 550, response: 5.7.1 Unable to relay
for cath...@wrighcity.k12.mo.us)]/"

I am running eventum on a Linux box and sending mail to an Exchange 2003 box. I
know my supervisor changed some settings on the Exchange box, but I have no idea
what he did and I do not know how to fix it.
