There was a 50% increase in spam on the Thursday just before Telecom switched its Xtra email platform to Yahoo, says Thom Hooker, director of operations at Auckland-based secure email software developer SMX.
However, Hooker believes that was probably coincidental. He says he doesn’t see any technical reasons why the Xtra migration would lift spam levels unless the spam filters were down during the changeover.
“Rather, it confirms the overseas trend of either new viruses or botnets. However, a lot of the connections and spam are coming from domestic ISPs,” he says.
The increased level of spam has continued.
“A large number of computers are not being patched. There are 400-500 in New Zealand infected every day,” he says.
SMX pitches itself as offering a service to clean mail of viruses and spam to 99.97% accuracy.
