We want to be your spam filter service provider!

Spammers lie about almost everything in email!

They cannot lie about the links they want to send you to, or the images they are trying to show you.  Over 90% of spam today includes a link to a website, or an image reference from a website.

What makes us unique?

We have developed a unique technology for use with our spam filter service that we call Stop and Dig.  This technology allows us to stop the processing of an email in order to dig the actual site referenced in the email.  We developed our first URL based spam filter in 2000.  Today we are in our third generation of technology and still going strong.
Information about Stop and Dig explains in more detail how we filter spam by using domains in the email.

NOTE

We are not accepting new customers at this time.

More information

Why purchase just a spam filter when you can also gain so much more from having our managed spam filter service?  We become your first line of defense for email, and we mailbag your mail if your server is offline for any reason. 

Backup MX providers claim to backup your mail if you go offline, but they can make the spam problem worse by not filtering for spam! Spammers then attack the backup MX provider.  We can safely act as your backup MX for email without causing you to receive more spam. 

Many companies refer to us as a third party spam filter (or 3rd party spam filtering) system.  What this really means is that we are an offsite spam filter that works between spammers and the target mail servers.  This can be your mail server, or your customers.

Our Philosophy

We are extremely passionate about protecting users online from porn spam and other objectionable email.  No spam system filter service can block 100% of spam, but our goal is to block 100% of the porn spam that you receive.  We may miss an email offering you an online degree, but we never want to miss anything explicit.

More Capacity

We now have the capability to process more than 3 million email messages per day!  We have recently upgraded to dual processor servers in each and every mail server.  Our server array processes over 4 terrabytes of email each month.
