Spam and Virus Filtering Testimonials
What People are Saying about Junk Email Filter
Here are a few statements from customers who are using Junk Email Filter:
John C. Dvorak of PC Magazine says he can no longer test spam filter software because he no longer gets spam. On This Week in Tech John raves about this spam filter. You can listen to it here. (8 minutes audio)
At first I thought John Dvorak was blowing a little smoke when he was talking about his experience with your service, but figured it was worth a try even if we got some partial relief from the spam that we were getting.
After flipping the switch, my overnight spam count went from 30-50 to zero.
Our coordinator, who gets the output from a couple of webforms on our website, saw her overnight spam count go from 50-100 (depending on how badly the forms got hammered by spammers) to zero.
This service is gold. I'm letting everybody I know about it and trying to talk our web provider into reselling it to her other customers. Thanks for offering such a great value.

Creative Commons has been using his service since last summer. I don't get much spam delivered to my creativecommons.org inbox.
Thanks Marc!

Larry Lessig posted this on his blog about our spam filter.
So the most significant change in my technology-related life in the last year is the elimination of spam without a white-list technology. I used to use Mailblocks for my main account, but Marc Perkel convinced me to try his own Bayesian spam filter.
I'm on record saying such systems could never work. I was wrong. Marc's system is amazing. I get endless email. His system filters the mail into three boxes -- my inbox, a low probability box, and a high probability box. I have never found a mistake in the high probability box, so I no longer look at it. I very rarely find a mistake in the low probability box, so I scan it about once a week (maybe 1% error). And it is almost fun to get an error in my inbox, reminding me that there still is this problem of spam out there.
I've had my domain names and email addresses for over seven years. With my active internet lifestyle, I am probably on every spammer's list out there. But I don't receive any of that spam, I get 100% real email, just the messages that I actually want to get.
If you want to know what it feels like to be spam-free then you should use Marc Perkel's spam filtering -- it just works!

We are an internet service provider that manages hundreds of servers for an international customer base. Prior to using Marc's filtering system, our company inboxes would receive hundreds of spam messages a day in many cases. In fact, the spam situation got so bad that our support staff was spending more time getting rid of the junk from our helpdesk than actually supporting our clients. Not only was the spam very annoying, but it was causing us to lose valuable time deleting, and in some cases, missing some very important sales leads.
At first we were apprehensive to switch to Marc's system since we did not want to risk any downtime during the DNS switch. We quickly learned that once we changed over, the switch occurred flawlessly with no mail lost during the process. Since the day we made the switch, the amount of spam we used to get was DRAMATICALLY reduced. So much in fact, that our staff thought there was a problem with the server since the core volume of mail dropped to nearly nothing. We then realized the true impact of this technology. We have yet to have any false positives, and get all of our mail we supposed to receive- every time. The amount of spam messages is not cut from 100+ per day down to less than 3 or so PER WEEK!
I cannot say enough great things about this technology. I am not sure how Marc achieves such accurate filtering, but it works, and very well at that.

We are very happy with the level of service we continue to receive from your service at junkemailfilter.com. I believe there exists no easier, more effective and absolutely no better value spam filtering service available anywhere.
I have recommended your service to my peers over the past few years. When they hear the cost they just roll their eyes in disbelief. Your service is such a great value that I think they do not believe me.

This morning, when I went to do my usual "time to clear out all the crap the built up overnight" there was nothing. NOTHING! Usually there's 3000-5000 messages in there, 70% of which have pretty much the same three subjects modulo the random crap they tag on the end, and I'd need to add that to my list of strings to whack, while spamassassin chugs away with 16 child processes running at full bore, so that by 11am or so the queue would finally be drained.
And today, there was nothing at all.
I had written some programs to do spam queue monitoring, some of which were really clever. I did similarity matching across subject lines to find buckets of spam that to delete. I was streaming the logs into a parser that would add IP blocks for addresses that crossed assorted thresholds. Stuff like that. But it's just gotten so much worse in the last 18 months and then again the last 3 months, that spamassassin couldn't keep up with what got through the front line filters. I knew I could just keep piling on layers and barriers, but it was a losing battle, and all I want is to be able to read my email in peace, ya know? I'm not interested in ongoing battles with assholes clogging up the pipes for their own profit; I have better things to do with my life.
Yesterday evening, I shut off all my scripts and filters, and the queue has remained empty ever since.
And now...I was tailing the logs this morning and the server looked positively bored. What makes me happy is that there's a couple dozen email lists I host for friends for free, some of which are kinda busy. And sometimes mail delivery would be delayed by hours if I compared the sent times with the received times. Now...less than a minute, consistently. I'll be pitching your service on a couple of them later today (or within a few days, when time permits), as well as up on hell.org.
Thanks again,
Mike Begley - hell.org
