Struggling to cope with increasing volumes of spam, Deakin University was forced to redeploy its Linux e-mail servers and implement an alternative system for e-mail security. Craig Warren, Deakin's operational service provision manager, said the Linux servers running antivirus and spam filtering software were effective for about three years, but "the spammers were steadily beating us".

As a result the university has implemented two IronPort c300 e-mail security appliances. "We were continually spending time fine-tuning our detection and prevention, but the intruders were quicker than we were," Warren said.
