k Sunner. The chief technology officer of E-mail management company MessageLabs, Sunner oversees a network that processes 4.5 million letters each day. Servers operated and maintained by MessageLabs manage mail delivery and routing for a number of companies, including Bank of England and Condé Nast Publications. In fact, all of MessageLabs’ customers are corporations whose daily E-mail output and inflow has soared with the growth of the Web. “E-mail usage has increased massively in the last couple of years,” he says. Indeed, MessageLabs estimates that it has gone from 10 a day per employee as recently as two years ago to more like 20 or 30 now.

The implications for Corporate America are equally huge. According to E-mail researcher and consultant David Ferris, companies can expect the volume of E-mail coursing through their servers to grow 60% to 80% in 2002. And as individual messages grow in size - they’re now more likely to contain memory - companies could end up paying 100% to 150% more just this year on systems to store and manage those messages. That’s why tech consultancy Radicati Group expects demand for soft ware that manages E-mail, such as Microsoft Outlook and Lotus Notes, to grow from $2.6 billion in sales today to $4.4 billion by 2005. Too much of this money will be spent in controlling pure junk. About 20% of the E-mail MessageLabs manages is unwanted, according to Sunner - who adds that about 1.25% of all the E-mail his company moves contains useless attachments. Already, the cost of handling spam（垃圾邮件）is estimated at $8.6 billion worldwide, according to a 2001 European Union study. And the barrage of pornographic spam has made some companies worried that employees might sue on grounds of disturbance arising from exposure to unwanted unpleasantness.
