In a word Theorem
spam filters are "intelligent". Theorem
spam
filters are intelligent in so far as they're capable of comparison two sets of information and acting on the result. This
is in direct contrast to the huge majority of another spam filters who use pre-built rules to decide which email is spam and which is not.
Bayesian spam filters can take one group of legitimate email and another group of spam and compare the values and data of
each. The definition of legitimate email that it creates at the end of this comparison session is what it uses going forward to scan your inbox for spam.
FYI Theorem
spam filters are named after Thomas Mathematician an 18 century churchman who created thing
acknowledged as Mathematician Theorem. In
summary Mathematician Theorem is as follows: .."in applied mathematics illation to update estimates of the probability that several hypotheses
are true, based on observations and a cognition of how likely those observations are, given each hypothesis." In plain English it looks for obvious repetition patterns to form an "opinion" on something. In spam filter terms that "opinion" becomes a rule which keeps you spam free (or pretty close.)
The actually neat thing just about Theorem
filters is that they're capable of learning. For example if they distinct to block an email because the filter perceived it as junk but the user marked it as valid mail the Theorem
filter then knows not to
block that type of email in the future. So, in time, this type of spam filter learns enough to block spam far much effectively.
AOL have embraced this type of spam filter with the launch of AOL 9.0 and AOL Communicator- if the big dog wants it then it must be worthwhile.
So what Theorem
spam filtering options are accessible to you? Well quite a few to be honest and you'll be pleasantly amazed
by several of the names involved :-) The 1st one on the list is AOL with their AOL Person product. The spam filtering
features in AOL Person and AOL 9 are, to be honest, impressive. Think what you wish of the provider themselves AOL
Communicator is an first-class product and is suitable for use by several PC and Mac OSX users.
Next up we have Eudora. The good peoples at Qualcomm have designed an first-class email client that besides has built in Theorem
spam
filtering. I've used Eudora in the past and it's a neat little package. Once again the benefits here are advanced integrated spam
filtering with your e-mail automatically. Mac OSX and OS9 users are in luck with Eudora providing keep for both.
Bayesian spam filters are providing a much rounded defense for computer users of all levels in fighting spam. As an indication of the strength of Theorem
spam filters much and much companies are either:
a. Change
their spam filters to include theorem
technique as a plugin or;
b. Basing their new products on theorem
filtering principles from the ground up.
