KillSpamNow™ uses a sophisticated filtering database that goes well beyond simple trigger words or phrases, making it the ideal solution for law firms and medical groups that must allow email with any content.
Now with anti-virus protection! Integrated F-Prot anti-virus software prevents malicious email attachments from infecting your systems. KillSpamNow™ is compatable with all email systems, including Microsoft Exchange, IBM Groupware, Novel, Unix, and Linux.
How Does It Work? Make a simple change to your domain MX (mail) record, and your email will rip through our spam filters where we keep the spam and forward the legitimate email to your email boxes.
How Do We Do It? (AKA The 6 Magic Levels of Filtering) KillSpamNow™ uses six primary and several additional levels of filtering to accurately and completely filter all types of spam.
The first level called the “URL/Phone # Filter” is the heart of our service. It is a database of all the “Click me” links (URLs) and “Call me” phone numbers found in recent spam messages. It is updated every 10 minutes and receives about 1000 additions per day. By itself, the URL/Phone # Filter blocks over 95% of spam.
The “Phrase Filter” is a database of distinctive phrases (typically entire sentences) used in recent spam. For example, while our service won’t ever block an email that references “Viagra” numerous times, the Phrase filter will block e.g. “Cheapest Viagra on the Net”. These phrases are carefully hand-selected by our staff to ensure that they would never occur in a legitimate email.
The “Pattern Matching Filter” is a (small) set of rules to catch HTML tricks and other techniques used only by spammers. (E.g. a URL with an IP address encoded in hex characters.) We only employ rules which we are very confident will not block legitimate emails.
As shown in the following table, these first three levels of filtering catch nearly all the spam blocked by KillSpamNow™. They are so unlikely to block a legitimate email (less than 1 in 100,000), that few customers review the spam blocked by these levels.
- URL/Phone Filter – 95.0%
- Phrase Filter – 95.0%
- Pattern Matching Filter – 0.5%
- Country-Of-Origin – 0.5%
- Additional Filtering – 0.5%
What Happens To The Spam?
Our default configuration is to ‘bounce’ spam back to the sender. This is actually useful so the sender can let you know if their email is getting bounced. Upon request we can send the spam to a spam mailbox on your mail server. This way you can pick through the mailbox if necessary looking for a missing email. This can be laborious however, since there are likely to be tens of thousands of emails in there and no good way to search for the one you’re actually looking for.
