MessageLabs reported that the percentage of "unauthorised"
e-mails sent had increased from under 40% in April to 55.1% of all
e-mails sent during May. SpamTrap, another filtering company,
revealed that in the same month 55.8% of all e-mails sent to its
customers were spam.
The figures come just a few days after Ryan Hamlin, general
manager of Microsoft's anti-spam technology and strategy group,
told a conference at the company's Mountain View, California campus
that the volume of spam sent is expected to increase to 65% of all
e-mail in 2004.
He added that concerted efforts by the software industry and
government should eventually stop spam, although it may take up to
two years.
