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.

How do I set up XE-Filter and my outsourced filter service?
|
|
1) |
Have your Internet service provider modify your domain's MX record to
point to the static IP address of the machine running
XE-Filter. |
|
|
2) |
Inbound email will flow to the XE-Filter
machine. Here XE-Filter's
multiple layers of protection refuse all
unwanted messages. |
|
|
3) |
Filtered by XE-Filter, the permitted email is redirected to the outsourced
email filtering service for its usual antispam filtering. |
|
|
4) |
End users receive their email as normal
but with much less foreign spam. They do not have to change any
settings. |

More Questions: XE-Filter and
Outsourced eMail Filtering Services |
|
My outsourced filtering service already filters spam. Why do
I need XE-Filter?
|
An outsourced filtering email service cannot provide all of the
extended protection offered by
XE-Filter. This includes filtering by country of
origin and other tactics that supplement any outsourced filtering service.
|
|
Why can't my service just add "Country-of-Origin"
filtering? |
Every business is different, so every business will ban and allow
email from different countries. It is unlikely that an outsourced filtering
service could implement this form of XE-Filter
protection.
Spam is a global problem and originates from many foreign
sources. XE-Filter easily eliminates this spam. |
|
|
What IP is used when
configuring XE-Filter as the destination for filtered
messages? |
Check your current DNS MX
configuration and note the IP address set for your
domain. This will be your outsourced filtering
server.
This IP is then used with XE-Filter as
the destination. This IP setting is actually
in the IIS SMTP server configuration. CMS technicians will
assist in this setup.
