14 ANTI-SPAM SOLUTIONS TECHNOLOGY REPORT
Test report
The Interface (continued)
The Spam Filter section under the major heading of Email deals with the
more universal settings and as such has a link that allows for the quick
turning on of spam functionality with a single tickbox. There is also a link
here to set the spam thresholds and to decide what the device should do
with suspected spam. The ability to use the SpamCop blacklist can be
turned on or off, and there is the opportunity to reclassify individual mails
using a MID value from a specialist header that the Netpilot Plus adds in
called X-Spam-Reclassify. Finally for this section there is the option to
view some statistics about Spam and genuine mail that has already been
learnt. The interface also notes that the inbuilt Bayesian spam adjustment
starts when 200 of each have been through the system.
The NetPilot plus has
several options for
dealing with suspected
Spam – it is possible to
deliver it as normal with
extra headers or to
quarantine it on the
device itself. Alternately
the administrator can
choose to have the
message delivered to
the administrative
mailbox, either as a
copy of the original or as an attachment. Although the device adds in extra
headers to emails, it does not currently allow for the alteration of the
message subject line to reflect the nature of the email. The device leaves
it up to the client email program to interpret these and mark them up as
appropriate, however the manual makes this clear from the outset, and in
normal corporate usage the quarantine would be used so that messages
would be unlikely to be delivered to the end users.
