How does XE-Filter work with an outsourced filtering service?
XE-Filter improves the effectiveness of outsourced email filtering services like Postini or Microsoft’s FrontBridge and gives you control of additional filtering techniques. These services do not historically filter incoming email by the “Country of Origin” of the originating email server. This “hole” in their service increases the total volume of email that must be filtered. With XE-Filter in place, the volume of spam is reduced before it ever reaches the existing outsourced email filter. This improves server efficiency and reduces the number spam messages that may pass through an outsourced email filtering service and reach the intended recipient. When using XE-Filter with an outsourced filtering service, a company must have their own domain name, business grade Internet connectivity and static IP addresses.
