My Spam analysis for July 7 - 13, 2008
This is the latest entry in a series about classifications of spam, according to my custom filter rules used by the anti-spam tool, MailWasher Pro.
MailWasher Pro is a spam screening program that goes between your email servers and your desktop email client (application). It uses a variety of techniques to recognize what is and isn't spam, including a learning filter and user created custom filter rules. I personally write and use MailWasher Pro custom filters to detect and delete most incoming spam email. I have created and published a large assortment of spam filters which "plug-in" to MailWasher Pro, to flag or delete known spam. You can read about them, or download and use them in your own registered copy of MailWasher Pro.
MailWasher Pro has a "Statistics" display page that breaks down the types of spam it has deleted, listed by categories. Each program and user-created filter has a name and when a measurable percentage of spam is matched by a particular filter it shows up in the Statistics, with its percentage shown next to it. The percentages for various categories of spam listed below are taken from my MailWasher Pro "Statistics" page.
The category "Other Filters" combines several of my custom filters which did not receive enough spam to rate a measurable percentage, thus were all grouped into the one category; "Other."
MailWasher Pro spam category breakdown for July 7 - 13, 2008. Spam amounted to 53% of incoming email this week.
