The move follows a detailed report last February by an internal advisory committee which found that spam accounted for at least half of all incoming email. The University was also hit by a succession of email-borne viruses that brought its mail systems to a halt.
The Barracuda system handles more than 150,000 email addresses served by the network's mail aliasing system. WSU reports a sharp decline in spam since the system was introduced.
Part of the attraction of the solution for the budget-conscious educational establishment was the fact that Barracuda charges a flat fee rather than on a per-user basis.
