Spamihilator's Word Filter examines every incoming mail. Therefore, it uses a list of well-known words that often appear in spam mails: the so-called Spam Words. Every one of these words has a certain probability.

By default, the sum of the probabilities of all spam words found in one mail must exceed 100% in order for Spamihilator to recognize this mail as spam. You can affect this value by altering the filter's aggressiveness.

Furthermore, you can add your own spam words or change the probability of existing ones.

Spamihilator's Word Filter has been improved a lot lately. Now it also supports regular expressions!

With regular expressions you can search not only for simple spam words but also for patterns that represent a spam word in a mail. For a tutorial on how to use regular expressions visit the following site:

How to use Regular Expressions

Click on “New…” to add a new spam word to the list. A window will open where you can enter the expression (e.g. advertisement) and then enter a probability for it as a percentage.

You can change the value of existing spam words by clicking on “Edit…”. Pre-defined spam words can also be edited.

If you want to delete a spam word from the list, simply click on it and then click on the “Delete” button.

The option “Ignore HTML tags” skips HTML code while searching a mail for spam words.

By default, the sum of the probabilities of all spam words found in one mail must exceed 100% in order to recognize this mail as spam. You can affect this value by altering the filter's probability threshold. This is the value that must be exceeded when the filter calculates the sum of all spam words found in one mail in order to recognize this mail as spam. The lower this value, the more often mails will be blocked.
