How command-and-control expert controls spam menace

  • 10 May, 2007 11:11

<p>Businessman Richard Newton, CEO of Videowall Pty Ltd, was receiving about 300 spam emails a day in his in-box, despite using Microsoft’s anti-spam tool.</p>
<p>Other staff were also receiving significant amounts of spam, reducing productivity in the busy specialist audio-visual supplier whose solutions include command-and-control systems. Customers include major public companies, government agencies and sporting organisations.</p>
<p>On switching to the TotalBlock anti-spam solution, Richard found that his daily volume of unwanted emails dried up immediately.</p>
<p>He said: “My account has had a spectacular beginning with TotalBlock. The system just works, simply and very effectively, and we have had no reports of customers being confused about responding to the challenges.”</p>
<p>When Richard switched his firm’s staff over to TotalBlock, a few spam emails were received but these were insignificant compared to the previous volumes.</p>
<p>“TotalBlock is going to save many hours of work previously spent just maintaining our email system,” he said. “I have gone to the TotalBlock website to authorise some accounts and that has worked just fine.”</p>
<p>TotalBlock works by blocking ALL machine-generated unwanted email, using a challenge-response technique rather than commonly used filtering. TotalBlock builds a list of acceptable incoming email senders, using a customer’s address book as well as replying automatically to any emailers who are not on the allowed list, and no further emails are challenged. The reply contains a simple action that, when followed, adds the sender to the allowed list. The action can be as simple as replying to the challenge.</p>
<p>Peter Stewart, CEO of TotalBlock Pty Ltd, says that the only spam that eludes his challenge-response solution occurs when spammers take the trouble to respond to a challenge – and this happens only rarely.</p>
<p>Defence Force member Michael Campbell is also benefiting from a switch to TotalBlock.</p>
<p>He says: “I think TotalBlock is excellent – previously my in-box was often flooded with more than 100 spam emails a day, and TotalBlock has eliminated all of this. Now I’m using my mobile phone for email, which I couldn’t afford to do before because it would have been too expensive paying for all that spam.”</p>
<p>About TotalBlock</p>
<p>TotalBlock - www.totalblock.net - is an Australian-developed anti-spam solution that also guards against network overloads caused by storming, harvesting and denial-of-service (DoS) attacks. It works by blocking ALL machine-generated unwanted email, using a challenge-response technique rather than commonly used filtering. TotalBlock builds a list of acceptable incoming email senders, using a customer’s address book as well as replying automatically to any emailers who are not on the allowed list, and no further emails are challenged. The reply contains a simple action that, when followed, adds the sender to the allowed list. The action can be as simple as replying to the challenge. Since this authorisation process requires human intervention, it bypasses drone machines that spew out huge volumes of spam. The TotalBlock solution also features a free Webmail service.</p>

I would recommend this device for families and small businesses who want one safe place to store all their important digital content and a way to easily share it with friends, family, business partners, or customers.

It’s easy to set up, it’s compact and quiet when printing and to top if off, the print quality is excellent. This is hands down the best printer I’ve used for printing labels.

Brainstorming, innovation, problem solving, and negotiation have all become much more productive and valuable if people can easily collaborate in real time with minimal friction.

The print quality also does not disappoint, it’s clear, bold, doesn’t smudge and the text is perfectly sized.
