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.

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.

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.
