XE-Filter: IP address based coutry filter for email

XE-Filter: Spam Origin Study

Filtering Spam eMail by its "Country of Origin"

DOWNLOAD XE-Filter
Foreign eMail Reduction Stats
XE-Filter Main

Studies vary with location, date and period of testing but historically, most spam email messages originate outside of the United States.

CMS uses XE-Filter and actual email traffic to determine the "country-of-origin" for messages received by Computer Mail Services, Inc. mail servers.

What does this data mean?

Large percentages of spam originate in well defined areas of the globe.
Almost every country in the world has been the origin of some type of spam email
Instantly eliminate 60% to 80% of all spam before it reaches your mail server by blocking email from top spamming countries.
Even excluding the USA, blocking the next 10 top spam generating countries still eliminates over 50% of spam email.
Existing antispam filters operate with a higher degree of accuracy with country-of-origin IP address blocking in place.

Benefits any company with a well defined "Business Region"

Historically, most spam email originates in the United States. For businesses exclusively operating in other areas of the globe, XE-Filter can be configured to receive email only from those areas of the world.

The chart below demonstrates, using the CMS study data, how a company doing business in known, well-defined areas of the world can use XE-Filter to significantly reduce the amount of spam reaching their mail servers.

  Business Region Instant XE-Filter Spam Reduction
  USA Only 87.7%
  North America Only 85.0%
  Europe Only 57.25%
  Asia Only 76.2%
  South America Only 86.3%

After XE-Filter instantly stops up to 80% of all spam before it reaches your mail server,  any existing anti-spam product can continue the filtering process.

Filtering email by "Language Type" is not enough

Existing spam filters often try to ban foreign email by determining the language type in the message body or subject line. 

Since English language messages can easily originate in non-English speaking countries, this is not enough.

XE-Filter eliminates this spam loophole through its "country-of-origin" technique.  See the XE-Filter FAQ on this subject...

The study was done during the month of November 2006.  Results will vary by location and duration of testing periods.
