Spamfire.net Remote Filters and your Privacy
Spamfire now includes a new feature called Spamfire.net Remote Filters.
This feature sends small parts of some of your emails directly to the
Spamfire.net servers for filtering. At Matterform, we have great respect
for your privacy. This page explains how we use the information that Spamfire
transmits to our servers.
- Turning it off. Spamfire Desktop ships with Spamfire.net
Remote Filters turned on by default. You can turn it off at any time
by choosing Preferences from the Edit
or Spamfire menu, clicking the Filters
tab, and unchecking the box labeled Use Spamfire.net Remote
Filters. However, you will see a drop in Spamfire's accuracy
if you turn this feature off.
- What messages can trigger Remote Filters. Not all
messages trigger the Spamfire.net Remote Filter feature. The Remote
Filters are only used when Spamfire needs additional assistance in identifying
- Messages from friends on your Spamfire Senders list never trigger
- Messages from known spammers on your Spamfire Senders list never
trigger Remote Filters.
- Messages that get identified as spam by the Spamfire local filters,
either the built-in filters or filters that you create, never trigger
- What information gets transmitted. When a message
requires Remote Filters, Spamfire does not transmit the entire message
to Spamfire.net. Spamfire extracts only the URLs that appear in the
body of the message and then transmits the domain names (not the full
URLs) to Spamfire.net. Neither the body text, the sender name, the subject
nor any other portion of the message is ever transmitted.
- What information gets stored on our servers. Our
server maintains an aggregate log of all the domain names that have
been transmitted to us. The log contains only a list of domain names
and the number of times they have been looked up. We do not store any
link between a domain name and your email address or IP address or any
unique identifier. If a domain name is transmitted to us that is already
on our whitelist of known non-spam sites (such as yahoo.com or msn.com),
the domain is not logged in any way.
- How we use the information. We store this information
only to assist with our spam analysis methods. It is not used in any
kind of marketing effort and is not shared with any third parties.
