Commtouch Survey: Nearly 90 Percent of Service Providers Have Had IPs Blacklisted in the Last 12 Months

    Commtouch Survey: Nearly 90 Percent of Service Providers Have Had IPs                       Blacklisted in the Last 12 Months  PR Newswire  MCLEAN, Va., Dec. 12, 2013  MCLEAN, Va., Dec. 12, 2013 /PRNewswire/ --Today, Commtouch published results of a poll among recent Don't Risk the Blacklist – Stop Outbound Spam webinar participants. The December 4^th poll of the Commtouch webinar attendees shows that nearly 90 percent of their respective organizations have had an IP address appear on a blacklist in the last 12 months.  (Logo:http://photos.prnewswire.com/prnh/20130731/MM56946LOGO)  The most common reason for blacklisting remains outbound spam, with the most popular outbound spam sources being:    oZombies, which are responsible for sending approximately 85 percent of all     unwanted email messages, send spam directly to the Internet using port 25   oUser accounts or domains created exclusively for spamming   oCybercriminals using compromised user accounts to send out spam  Spam is easily traced to the sending IP range, resulting in the addition of this range to Realtime Blackhole Lists (RBLs or IP blocklists). Most service providers use these blocklists to enforce message blocking rules – and as a consequence, legitimate email sent from these ranges gets blocked.  Being blacklisted often has a significant business impact, including:    oRemoving the addresses from blocklists takes time and resources   oLegitimate email senders drain support staff time with complaints   oIn a worst case scenario, customer churn is caused by the reputational     damage  "Traditional approaches, such as blocking port 25, reversed inbound spam filters, or throttling, have limitations – and are ineffective in the end because they treat symptoms, but not the underlying problem," said Lior Kohavi, chief technology officer at Commtouch. "Therefore, it is important to protect mail systems with a specialized outbound anti-spam solution that also pinpoints the spamming source. As the common characteristic of all spam is mass distribution, such a solution must be able to detect local and global recurrent patterns."  During the live webinar, Commtouch probed what process aggrieved parties set up to get their IP addresses removed from blocklists. Half of all interviewees stated phone calls and emails sent by their operations department helped to remove their address. Another 38 percent said, "We make it up as we go along," when asked how their organization handles blocked addresses. Only 13 percent of the participants stated they would not have to do anything because there were automated processes in place. None of the participants chose the answer "No process, as we never get blacklisted."  The Commtouch poll results clearly indicate that outbound spam is omnipresent and causes significant issues and cost for businesses of all sizes.
