Wizcrafts' MailWasher Pro spam filters updated today

October 6, 2013

Today, October 6, 2013, I published a large update of my custom spam filters for MailWasher Pro, a desktop and mobile device spam-filtering program.

Normally, I may update a couple of my spam filters a week and create a new filter once a month. However, due to a sudden enormous increase in the amount of spam for pharmaceuticals, plus malicious messages, I have created 5 new spam filters and changed the names of two existing filters.

The new filters deal specifically with new botnet spam templates used to promote the fake "My Canadian Pharmacy," along with other fake pharmacies selling illicit prescription drugs and useless diet capsules. Also, I created a new filter to detect a variation of a malware link scam.

New Spam Filters

My new anti-spam filters published during this calendar week are as follows.


  1. CNBC Diet Scam (Green Coffee herbals) (Yuk!)

  2. Fake Pharmacy Spam ("My Canadian Pharmacy")

  3. Empty Return-path

  4. Outlook.com & WhatCounts

  5. USPS Delivery Scam (Courier scam with malicious links to exploit kits)

Changed Name Filters:


  1. "Possible Pump and Dump Scam" renamed to "Empty Return-Path"

  2. "URL Shortener Link" (new xml filter version) to "URL shortener, or 2 digit country code link"

  3. "URL Shortener (Spam) Link" (old version 6) renamed to: "URL shortener, or 2 digit country code link"


My anti-spam filters will detect, flag, or auto-delete over 80% of the spam a typical email recipient receives. This number is from my own MailWasher Pro Recycle Bin logs.

Note, that I already have a published spam filter that detects anything spoofing CNN news. The last few days has seen a huge influx of fake "CNN News Daily" email scams with links to (mostly) Russian websites that sell the green coffee extract crap. The latest round have the subject: "Slim Secret Shop." My spam filters delete them automatically.

What MailWasher is and is not capable of doing.

MailWasher Pro is a desktop, or mobile device spam-filtering application that receives email from POP3 and IMAP email servers to which you have been granted access. The program scans the headers and message body contents to determine if the message is legitimate, or is or may be spam. While the program contains a strong learning filter and other optional anti-spam tools (e.g. blacklists), the ability to craft custom spam filters makes it stand out.

Legal Disclaimer:
I have been a happy user of MailWasher Pro since its inception. Now, I am both a customer and an affiliate. I earn commissions whenever somebody buys into the program through my affiliate links.

That said, I'm not trying to scam anybody into purchasing MailWasher Pro. Maybe you have a different spam filter solution, or are stuck using browser-based web-mail. MailWasher can't help people who use http web-mail through their web browsers. It is strictly for POP3 and IMAP email where you use a desktop or mobile email application to send and receive messages over the POP3 or IMAP protocols. People using desktop email clients like Windows Live Mail, Outlook, Outlook Express (deprecated by Microsoft), or a similar stand alone email program, can benefit from running MailWasher Pro ahead of their email client. I set MailWasher to check for new mail every 10 or 12 minutes, but turn off automatic checking in Windows Live Mail. Only after MailWasher has deleted any spam or unnecessary email, do I download legitimate messages into Windows Live Mail.

I won't bore you with all of the details; you can read them yourself, here. They offer a 90-day, no questions asked money back guarantee, if you aren't happy with the program.
