What is Message Sniffer?

Message Sniffer is a command-line anti-spam scanner that uses advanced pattern recognition technology to accurately identify spam. The engine is multi-platform running on Windows, Linux and BSD systems. A unique, downloadable spam database is available via subscription and is updated multiple times daily by spam analysts and intelligent monitoring systems.

Message Sniffer captures more than 98.5% of spam without tuning.  This is not marketspeak! This statistic is calculated by our monitoring system using data from spamtraps, user spam submissions and a comparative analysis with several dozen high quality spam tests.

How Does it Work?

Message Sniffer is about raw power and effectiveness.  Unlike other systems, the engine requires no "learning period" and does not rely on DNS based spam blocking lists (DNSBLs) which can be slow to respond.

The Message Sniffer utility does not actually filter messages itself. Rather, it integrates with your email system and identifies pattern matches which indicate that messages are likely to contain unwanted content.

Unlike many anti-spam products that scan for content, Message Sniffer's tests search for combinations of spam features including message sources, common obfuscation techniques, email and url targets and fragments, and even coding styles.

What Can I Use it With?

Message Sniffer hooks into your email server and works with many popular products on the market today such as:

ARM Research has also developed products based on the Message Sniffer engine, such as Assert! for Exchange and IIS SMTP.

How Do Our Customers Feel about Message Sniffer?

"The results are amazing. All of my users think that I am a hero, but I owe the credit to you."
- Joe Rymski (Colorado State University)

"After using this product for a year and a half, I can honestly say that MessageSniffer is the most powerful tool in our anti-spam arsenal. It is the heaviest weighted spam test out of the 45 that we run, and it is also the most effective. It also integrates well with in a Linux server environment and runs very efficiently."
- Bill Boebel  (Webmail.us)

"Awesome product - great support. This product catches 99% of the junk mail that enters my server. The junk mailers are getting smarter, and their messages are not failing the header tests anymore. Message sniffer actually scans the content and identifies against it's manually verified ruleset. As a bonus, it also catches many of the virus emails by their message content. Well worth the money."
