Mark.JUK writes: The CTO of Internet security giant Trend Micro, Dave Rand, has called for UK and EU governments to adopt tougher legislation against SPAM (junk email). Rand also urged Internet Service Providers (ISP) to help combat the problem by blocking email on port 25 and informing users when their computers begin unwittingly distributing masses of junk messages (zombie systems). However his comments have not gone down well with Internet providers who complain that blocking port 25 could cause a lot of problems and wouldn't necessarily solve the problem, with authors of malicious software adapting to use other ports or methods. Rand believes that ISPs are over playing the impact that such a block would have on their services. He pointed out that some countries, such as Turkey, were able to impose similar restrictions and saw a large reduction in the problem with only minimal gripes (e.g. Compromised PC's in Turkey dropped from 1.7m per month to 35,000).
