New Whitelist and Blacklist Features Enhance the Already Powerful eMail Filter

TROY MI — MARCH 8, 2007 — Computer Mail Services, Inc. (CMS), a leading email security and management software provider, announces the availability of XE-Filter v1.10, software designed to block spam email based upon its country of origin.

The XE-Filter v1.10 release features IP Address Whitelists and Blacklists that expand an administrator’s control over email operations.  With the XE-Filter Whitelist, email can be received from banned countries by designating an IP address or range of addresses.  Similarly using the blacklist feature, email from known spammers can be blocked from countries in the XE-Filter allowed country list.

Using “Country-of-Origin” filtering, XE-Filter can block email from any designated country.  Since the top spam producing countries are widely known, XE-Filter lets businesses receive email only from countries where they have business operations, suppliers or other contacts.

“Our company has experienced an 80% reduction in spam since XE-Filter was implemented. We experienced this change almost immediately. With the newly added whitelist functionality, we have been able to increase that reduction by an additional 5%. The application is straightforward and simple to use“, said Kevin Calk, CIO of ECOM PPO Advisors.

Simple in concept, cost-effective and requiring very little administrative effort, XE-Filter is the first country-centric spam filter.  Using the connecting IP address of the mail server attempting to send the message, XE-Filter determines the originating country and checks against an administrator-specified banned country list.  If the email originates from a banned country, the message is refused.

XE-Filter installs on the Microsoft Exchange 2000/2003 server that is the point of entry of inbound email traffic.  For non-Exchange sites, it can be installed on any PC acting as the gateway with the Internet.  XE-Filter works with existing anti-spam filters.

XE-Filter is available now with prices starting at US$195 per for 25 users or less.  A 21-day evaluation version of XE-Filter is available from the CMS website, www.cmsconnect.com.
