Legitimate messages were getting refused due to a bad virus definition.
System administrators identified a rule update to the anti-virus system used by the central campus mail routers. This rule was erroneously marking valid messages as viruses, causing legitimate mail to be rejected. As of 9:45, the rules were removed and the mail service was restored.
