Are we really as good at blocking spam as everyone says we are?
This filter was developed by company founder and all around tech genius Marc Perkel. Marc is a leader in the spam filtering industry and was behind several of the spam filtering technologies currently in use today. We share a lot of our technologies with our competitors and many of them share with us. In order to fight spam we all work together as a global team. And we at Junk Email Filter are proud to be part of that team.
Junk Email Filter provides one of the world's biggest and most accurate black list and the world's biggest white list of any spam filtering service. Our HostKarma DNS database is a free service that helps us and thousands of other servers block billions of spams a day. We also feed hash codes of incoming spam to several hash matching services allowing others to detect the same kind of spam that we identified first. Our filtering system is so fast at identifying new spam that we can eliminate nearly 100% of spam bot spam.
Email Privacy
We don't provide government access to your email!
We are dedicated to keeping your good email private. Privacy is in our opinion an absolute right. We do not disclose the contents of emails to lawyers, law enforcement, or government agencies. We will not comply with any subpoena that is not signed by a judge of appropriate jurisdiction (Santa Clara County California, United States). This means no NSA letter that do not have a judge's signature. We will fight any attempt of any government to spy on our customers. We will cooperate with law enforcement in cases where lives are in immediate danger.
We are not however like AT&T and other Telecoms that just hand over access to anything governments want to tap. It is our view that government exist solely for the purpose of serving the people and no other reason. Government spying for the purpose of gathering information on political dissidents for the purpose of oppressing free speech is fundamentally wrong and our spam filtering service will not cooperate with it.
Our servers support encrypted connections both incoming and outgoing. We encourage everyone to use encryption when sending email across the Internet. Additionally we do not normally store email on our servers except for the time it takes in between when we receive it and when we send it out. Most good email that passes through our servers stays in RAM and is never written to disk. That which is written to disk is deleted as soon as we send it on unless we are saving something for diagnostic reasons. We do however save spam in some situations for analysis and we share blacklist, whitelist, hash fingerprints, and other forensic information with others in the spam filtering business and with the public to assist those who are also trying to block spam.
We also encourage you to support the good folks at the Electronic Frontier Foundation in their tireless effort to protect our online privacy rights.
Technical Details.
The system is very easy to set up and requires no hardware and you don't have to reconfigure your existing email server. All you have to do is set your mail exchange record (MX) to our servers and incoming email destined for your domains will be delivered to us - we process the messages - and then pass the good email on to your existing email server. Its that easy.
- Protection - Virus Detection is very accurate. We block all windows executables and scan all other attachments.
- Defense - Messages containing viruses or spyware are blocked never reaching your server or your users.
- Accuracy - Spam Filtering is VERY accurate. Very little spam missed.
- Reliable - Multiple Servers in Multiple Locations

- Inexpensive - very low cost for one domain or all your domains.
- Fast - it only adds a few seconds to the delivery time of your email.

- Unique - Multi-Level Spam Detection to eliminate false positives.
How it works.
We catch most spam based on the behavior of the spammer rather than the content of the message. Spammers are on the run these days operating mostly through virus infected spam bots. Spam bots send spam differently that normal email servers. They try to sneak spam in the back door. They don't issue QUIT commands to close the connection. They often use email addresses mined from web sites and do dictionary attacks. These behaviors and others allow use to know a message is spam without having to look at the content of the message.
The two level spam filtering makes this service unique. Messages are classified on a points system using Spam Assassin. Messages that score very high are considered high spam and they are blocked. Messages that score between 5 points and 15 are considered low spam. These messages are flagged with special message headers indicating that they are "probably spam" and are passed on to your server. You can create filter rules to see these messages and route them to a spam folder.
The reason we do it this way is because no spam filter is perfect. But we deal with the fact that messages are missed or wrongly identified as spam in a way that helps to ensure that you don't lose any email.
If a message were falsely marked as spam - it would fall into the low spam classification. But with the high scoring spam removed completely - these false positives are far easier to find because they are in a much smaller pile of messages that are spam. This way the message is still delivered to you but because we get rid of the high scoring spam - there is far less spam reaching your server and it makes these false positives easy to find.
Here's a diagram of how the mail is processed:
What this means to you is - you don't lose any email due to the spam filter getting it wrong. The messages classified as low spam is often only 1/100 of the total spam sent to you. So what we do is bounce 99% of your spam and tag the remaining 1% as "probably spam" and pass it on to you.
Hosted virus filtering.
Although we still recommend that end users use anti-virus software on their workstations and laptop computers - we provide a second level of defense - and a better defense against viruses. We strip the virus messages before they ever reach your users. And we do a better job of it that workstation anti-virus software does.
Although companies like McAfee and Symantec keep on top of viruses - there is a lag time between when a virus first appears and when they discover it. And an even greater lag time till end users download new virus definitions which might be as little as once a week. This creates a window of exposure where your end users are unprotected.
We use a server side virus filter called ClamAV. Our definitions are updated hourly so we are more likely to stop those new viruses faster than workstation installed software will. Additionally - we block all Windows Executable attachments so even if a new virus is created right now - if it's a Windows Executable - it's not going to get past our filter. Our system gives your users far stronger protection preventing then from being infected and resulting in downtime - loss of data - and costly repairs.
Compatibility with your Existing Email System
Because of the way we are preprocessing email we are totally compatible with all other email systems. So it doesn't matter if you run Microsoft Windows, Linux, BSD, Solaris, Macintosh, or Netware - our system works. It is compatible with all other email server software such as Microsoft Exchange, Sendmail, QMail, PostFix, Exim or other mailer. And the best part is - you don't have to change any settings to make this work.
Your end users don't have to change any of their email setting either and is compatible with popular email clients such as Microsoft Outlook, Outlook Express, Mozilla, Netscape, Apple Mail, Eudora and others. Users can take further advantage of the spam filtering by creating a filter rule in their email client to route messages marked with the spam header tag to a special spam folder for later viewing.
Additionally - if your email users are using bayesian spam filtering already - our preprocessing will make those filters more accurate. These filters look at messages and learn what it spam and what isn't and with the additional header information your existing bayesian filtering will just start to work better leading to happier and more productive email users.
The bottom line is - this is a system that actually works to block spam - is easy to set up - and is well worth it. Do you want to spend your time deleting spam and viruses? Do you want your employees doing real work instead of deleting spam? If so - then this service sounds like what you need - email us with your details for a custom price quote.
