“In a recently-published white paper, research firm IDC advised that organizations choosing anti-spam technology should give consideration to innovative approaches such as Commtouch Software Ltd. Recurrent Pattern Detection (RPD) technology. The study said that RPD differs from other anti-spam technologies in that it detects spam using characteristics that spammers cannot easily change, and in that it detects and blocks spam in real time”

"We're approaching the bulk nature of spam," Drori said, "because spam is, by nature, a commercial activity, and depends on bulk. Most anti-spam technology looks at spam's content. The honeypot approach [setting up 'decoy' servers to catch unsolicited mail] blocks only 80 per cent of spam. Blacklist technology results are very limited. Our technology has two major advantages – it catches spam in real time, and it's content-agnostic."

IDC’s white paper, ‘Choosing the Best Technology to Fight Spam’, reviews spam trends and currently used anti-spam technology, such as honey-pot signatures, lexical and heuristic content analysis, Bayesian filtering, and sender authentication.

But it claims that the recurrent pattern detection (RPD) technology developed by Commtouch can overcome challenges facing the other technologies, by detecting and blocking spam in real time.”
