Outbound Spam Report Available From Commtouch

Commtouch : 10 June, 2010  (Technical Article)
The effects of outbound spam are covered in a research report issued by Osterman Research and Commtouch examining problems such as blacklisting and the dissatisfaction of customers which result from spam being distributed from internal servers
Spam sent from service providers' own networks is a serious industry problem, according to a comprehensive report "The Problem of Outbound Spam," by industry analyst firm Osterman Research and Commtouch.

In May, Commtouch commissioned Osterman Research to conduct the first ever study on the effects of outbound spam. The research was based on the survey responses of hundreds of service providers and email customers from around the world.

"Service providers are starting to realize that dissatisfied customers, blacklisting and other problems caused by outbound spam are issues they cannot ignore," said Michael Osterman, president and founder of Osterman Research. "By eliminating spam originating from within their networks, service providers can reduce their costs while improving the service levels they offer their customers."

Highlights of the survey include these findings:

* 78 percent of service providers surveyed said it is important or extremely important to identify the senders of spam within their networks as part of an outbound spam solution
* 75 percent said deploying an outbound spam solution will help them to improve their customer service
* 80 percent of email users surveyed believe that it is important or extremely important that their service providers actively ensure that spam is not sent out from their networks

Outbound spam is the spam generated within service providers' own networks. The source of outbound spam can include compromised accounts, spammer accounts, and zombie computers.

The in-depth report discusses:

* How serious the issue of outbound spam is for service providers
* How Internet Service Providers (ISPs), Web hosting companies and managed email providers are attempting to cope with the issue
* The effectiveness of their existing solutions when it comes to protecting them from having their IPs blacklisted
* Essential capabilities and characteristics required of outbound spam protection solutions

"Based on the results of this research study and our discussions with service providers, many providers that have tried to prevent outbound spam using various techniques are still suffering from false positives and poor detection levels," said Asaf Greiner, Commtouch's vice president of products. "The only way to effectively keep off of blacklists is to block outgoing spam while simultaneously targeting the sources of the problem - the spammer accounts, compromised accounts, and zombies."

Commtouch recently launched an Outbound Spam Protection solution, which stops outbound spam in real-time. It detects local spam (spam generated within the service providers own network) as well as global outbreaks, and also detects the source of the outbound spam.
