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.

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.
