Spam Hound uses information
uses online databases of spam senders to better detect spam.
A Blackhole is an online
database of computer addresses (IPs).
Computers are added to blackholes
for any number of reasons ranging from belonging to a company that continuously
and persistently sends out millions of spam, to computers which reside
in a particular country.
Blackholes provide very good
spam filtering as part of a series of tests like Spam Hound performs especially
when configured for an individual user.
For example a result that indicates that the email was sent from a server
in China (where security is notoriously lax) is not an indication of spam
if you regularly correspond with people in China.
However if you don't, it may be a good indicator that the email is spam.
Spam Hound's Neural Network
automatically learns what blackholes are relevant to you.
