MailWasher Pro Image Spam Filters Updated

CastleCops A new filter set for MWP users brought to you by Wizcrafts!

I just updated my most effective MailWasher Pro image spam filter to catch a new variant; jpegs instead of gifs. The updated filters are here.

The new rule, just under the "Restored From MailWasher Recycle Bin" rule, catches 99% of the image spam sent to me. It uses only one regular expression and is faster acting than the other rules that use more regular expression matches.

If you are not currently using a spam filter and are getting deluged with image spams for penny stocks, the combination of the email screening program MailWasher Pro and my custom MailWasher filters will reduce your visible spam to a tiny percentage of what you are probably seeing right now.

Note: The MailWasher Pro filters.txt does not go into the program directory. It goes into the MailWasherPro subdirectory under Documents and Settings\(your profile)\Application Data\. You can find this direectory and it's contents by opening MailWasher Pro, clicking on "Help," "About" and on the link on the bottom of the "About" box.

Get Norton 360

I have updated my MailWasher Pro filter rules again to block all of the current variety of image spam for junk stocks, pills and porn, effective 5/1/2007. If you have been using my filters and are still getting these image spam emails you should update your filters to the newest codes. I have also improved the parsing speed by reducing the scope of the Regular Expressions rules to the bare minimum needed to catch various types of spam.

My filters are here: http://www.wizcrafts.net/mwp-filters.html. There is a link under the iframe to load my current reduced filter set instead of the large, partially out-dated set, into the iframe. You can also download either filter set from that page.

Get Norton 360 Version 4.0 - All-In-One Security. If you have a non-current version of a Symantec security program and wish to renew your definition updates subscription, or upgrade to a new version at a discount, go to the Norton Product Upgrades & Renewals page.
